Starting out with the K40 and TWR-LCD

SeanMichael — Tue, 17 Jan 2012 17:40:15 GMT

So I am fairly new to developing programs with the Tower System in general, but I have done quite a bit of work on the Freescale HCS12 microprocessor. Anyways, I was hoping for a little bit of help. I have been doing quite a lot of research lately, to figure out exactly how I have to go about programming the LCD Screen. I still do not have any clue. I want to control it through the K40, as well as have the K40 control one or two other peripheral boards, such as the TWR-SER board. I was wondering if anybody could possibly point me in the proper direction, for the TWR-LCD. That is my first goal to accomplish along the way of this project. I really haven't found any documentation to tell me how to integrate the K40 and the TWR-LCD into a single project. So I am currently chasing my tail on this one. Any help would be very much appreciated.

Thanks, I did have all those files downloaded, but I never did figure it out how to actually get it all opened into CW 10.1 until today. So the tip was helpful, it got me looking in the proper location. Now I can start diving into it, and figure out what to do, to program the K40/TWRLCD.

I'm having the same problem. How do I get started programming the Tower kit using CW 10.1?

Re: Starting out with the K40 and TWR-LCD

SeanMichael — Thu, 26 Jan 2012 21:28:44 GMT

So I have a basic question about the installation of Codwarrior 10.1. I am working in my school using CW10.1 and it is installed on C:\Program Files\Freescale\.... directory. I did not install it, our ITS did. Anyways, While I was installing MQX 3.7. I know it gave me a warning, saying that I should make a folder on the C Drive itself, to avoid errors with read only files. So I did, it is installed under C:\Freescale\Freescale MQX 3.7..... The reason I am asking, is because i get a make error. It tells me that it can not locate a source file, for the EGUI demo, for the k40x256. The file that it is looking for is suppose to be on the C:/Program Files\Freescale\CW10_1..... Also, when I load in the demo, I have to right click on the project, and click on Edit Linked Resources, to change the MQX Directory. It is default set to look at the C:\Program Files\Freescale\Freescale MQX 3.7, and I simply change it to C:\Freescale\Freescale MQX 3.7, which eliminates a quite a few errors. When I am finished doing that, and I click Ok to exit the entire properties pop up page. I get another error. the error says as follows: Problem Occurred File\CW_10_1\.project is read-only. As of right now, I am think that this might be due to Codewarrior 10.1 being installed under Program Files on the C Drive. However, that is only speculation, and I am hoping somebody here can either confirm or deny this.

What is the path of the demo project you are trying to open? Is that path read/write able?

I would copy the entire project you are trying to use to a folder that you have read/write permissions on. You'll have to change some links inside the project, but that should eliminate the particular issue you are having.

Re: Starting out with the K40 and TWR-LCD

SeanMichael — Fri, 27 Jan 2012 23:35:04 GMT

Ok so I switched the the K60x512, because we had an extra one in the building. Also, I was reading the AN4452, which seems targetted toward the K60. So I decided to give it a try. The program compiles and all, however when I click debug, and wait for everything to load, I get an error. This one to be exact. I am not quite sure where this problem came from, and how to fix it. I googled it, and didn't really find much. I am going to give it a second try after writing this. So I was hoping one of you guys would happen to know what is causing this error. Do I need to update something, re install firmware, am I missing a jumper, or what....

What I did once I opened the K60 out of the brand new plastic packaging, was plug both the TWR-SER and the K60 into the computer, which then I used the P&E Firmware updater to flash the firmware on the K60 to the newest one out there. I made sure to remove the jumper from J10/JM60 the boatloader jumper, and then I made sure that I could move my mouse with the pre-installed quick start demo. played with the capacitive touch buttons, and put the TWR-LCD onto the primary side of the Tower Elevators. Which when I hit debug, to run the K60 eGUI project with mqx 3.7. I have a usb plugged into the K60, and the TWR-SER. Hmm... lets see. Switch 5 on the TWR-LCD are all on, and my dips from switch 1 are as follows. 1 off, 2 on, 3 on, 4 on, 5 on, 6 on, 7 on, 8 off. which leaves me with a white screen. Other then that, I haven't moved any jumpers at all on either the k60 or the TWR-SER.

Hopefully there is enough information to figure out what is going wrong, and thanks for the help by the way.

So I tried to debug the K60's Quickstart project, and I was successful. Which leads me to believe that there is some kind of error in the K60's debugger files in the EGUI demo project, for mqx 3.7. However, I am only a novice, so I am hoping for somebody who knows the K60 alot better then I do, to confirm or deny these accusations.

anthony_huereca — Tue, 31 Jan 2012 22:38:41 GMT

Starting with the Quick Start Demo was the best way to make sure your setup is working.

The error you're seeing is likely due to that the project is looking for the memory configuration file in MQX that is at the default location.

Go to Run->Debug Configurations from the menu bar.

Then select the the CW_10_1_twrk60n512_Int_Flash_Debug_PnE OSJTAG (or whichever you're using) configuration.

On the screen, there is a box that says "Remote System", and it has a drop down box selection. Click on the "Edit..." button next to that box.

In the dialog box that pops up, click on the "System" tab

Then there are two text boxes specifying the "Initialize target" and "Memory configuration". Edit the paths in those boxes to match where you installed MQX.

Then you should be able to download your code!

anthony_huereca — Tue, 31 Jan 2012 22:39:45 GMT

The best way to start is by going through the Quick Start Demo lab: http://cache.freescale.com/files/32bit/doc/support_info/TWRK60N512QSDLAB.zip

Hello,

I have tested the MQX 3.7 project in the eGUI package and worked for me. For some reason the project has lost the connection configuration and I created a new one. Attached my project. You can unzip in the same eGUI package location. \_Official_Demos\EGUI_D4D_Demo\TWR_K60N512

Let me know if it works for you. Otherwise I will guide you to create a New remote system connection for K60 and OSJTAG.

Best Regards,

Re: Starting out with the K40 and TWR-LCD

SeanMichael — Wed, 01 Feb 2012 00:09:07 GMT

Well sorry for being a pain yet again, but the program advances, to this box

Where I click on "No", to continue downloading the program. Which then nothing happens. It gets stuck like the follow.

And then that is the extent of it. I am using the BSP file from Freescale MQX 3.7/mqx/build/cw10/bsp_k60n512. The project I am using, is the one you just sent me, I have a copy of the original folder, but in the original folder, where I am running the program from. Freescale_embedded_GUI_SW/_Official_Demos/EGUI_D4D_Demo/TWR_K60N512 I deleted the original MQX_3_7 folder, and replaced it with the one you sent me. I did a clean project once I imported the file, because I got a make *** target error. It was looking for the main.c file in D:/working/...... On my computer, there isn't a D drive at all. Once I did that, it compiled, and got to the two screens I sent you. The entire time I wrote this message, I let it continue to run, and it hasn't moved at all.

I am starting to wonder, if it's me that attracts all these errors, and problems whenever I work on something new, or are there other people having just as many problems as I am getting the EGUI demo to simply run?

Anyways, I just want to thank everybody for the help that they have given me, and the help I am still receiving. I am also going to zip up my files and send them to you guys just in case. It is the bsp file from the mqx folder installed from mqx 3.7, aswell as the EGUI file you just sent me. I do not know if they will be of any use, but hey too much information shouldn't be a problem.

Hello,

That is warning message is not a real issue. That have been changed in CW10.2. It is a warning about Flash Configuration register that has been modified. Pressing no will flash the app. Is any app running? Do you have the right user_config.h bsp configuration?

Best Regards,

Re: Starting out with the K40 and TWR-LCD

Hello,

Your files work in my PC. I unziped in my eGUI folder and run perfectly. I changed the MQX variable from T:/ to my path to build. But the same connection worked fine in my system.

Two suggestions:

1. Upgrade the OSJTAG firmware with Pemicro application

Firmware Upgrade & Recovery tool

http://www.pemicro.com/osbdm/index.cfm

2. Be sure you have applied the patches in CW10.1

CW10 has a bit of a learning curve, but once you get a project going, you'll be fine.

As for your current problem, try hitting the pause button while the debugger is going to see where the code might be stuck at. And double check your jumpers (Section 3)

Right now the debugger is trying to run all the way to main() before breaking after you start debugging but seems to be getting lost somewhere. To start the debugger at the very first instruction, you need to modify an option in the debugger configuration.

Go to Run->Debug Configuration

Select the CW_10_1_twrk60n512_Int_Flash_Debug_PnE OSJTAG configuration

Go to the "Debugger" tab at the top of that screen

In the "Program Execution" box, select "Program entry point" instead of the default "User specified: main".

Then you can step through the code line by line to see where it might be getting lost. There will be some assembly at the beginning, but just keep stepping through and eventually you'll reach the hardware init code in C.

Hope that helps!

Re: Starting out with the K40 and TWR-LCD

SeanMichael — Wed, 01 Feb 2012 22:43:29 GMT

Ok, so I rechecked all my jumpers, they are all in the correct locations. I rechecked the updates, CW 10 is up-to-date. I reflashed the board using Pemicro. I copied and replaced my user_config.h file with your Luis Casado. The only difference was that in mine I had #define BSPCFG_ENABLE_IO_SUBSYSTEM 1, which I did not see in yours, and you have #define BSPCFG_ENABLE_TCHSRES 1 which, I didn't have in mine. So right now I have one error. which is the photo that follows. My question, is what is the best way to change the location in which CW is looking for that file. Last time, I hit clean project, and that didn't work out for me all that well. I made sure my initialize target, and memory configurations, in debug Configs, was set to the proper file directories.

I think I am going to wait until later tonight, when there is nobody else in the school lab, so I can take a video of what I do to set everything up. If I do, hopefully you guys will find what I am doing wrong. I did get the file to compile a few minutes ago, then it got caught up when I hit reset, and lost the OSJTAG. When I hit run, the screen just continues to stay white. Nothing ever pops up on it.

Once again, I really have to thank all of you for being patient with me, and helping out. I truely do appreicate it, and hopefully I am not drive you guys insane. With me, all the errors I usually have in class, it is usually something very easy to overlook. After finding it, and fixing it, my professors laughing at me and telling me to pay attention to the small details. I am really hoping that this is another one of those issues. I suppose time shall tell, and as for what Anthony Huereca said, about getting the program to work, and then being fine, that is what I was hoping for. Once I can get a working program that I can modify something small, then compile the code, and watch it change something on the screen. I am usually good at figuring out what I need to do from that point onward, to accomplish my goal. This part of the project should hopefully be the toughest part. Anyways, Thanks for all the input guys.

Hi,

The error should be removed doing a clean of the project. I have tested the eGUI package projects and your projects. BSPCFG_ENABLE_TCHSRES 1 is needed to get the touchscreen working on MQX + eGUI.

Try the eGUI bare metal example to check if there is a problem in the TWR-LCD settings. You can find here instructions:

Re: Starting out with the K40 and TWR-LCD

SeanMichael — Thu, 02 Feb 2012 18:54:17 GMT

Ok I have to be missing something. So this is what I just did.

1. I downloaded the JM128_BL_TWR_I2c.s19, that you linked in http://www.towergeeks.org/forum/topics/twrk60n512-and-tft.

2. I unplugged the TWR-LCD from the TWR-LCD.

3. I put SW1 to ( 1-Off, 2-On, 3-Off, 4-Off,5-Off,6-Off,7-On,8-Off)

4. Put the TWR-LCD into Bootloader mode, by holding SW3 and pressing SW4 while i had the usb attached to the computer.

5. I then unplugged the TWR-LCD and put SW1 to (1-On,2-Off,3-On,4-Off,5-On,6-Off,7-On,8-Off) and verified that all of SW5 was on.

6. I downloaded the eGui from www.freescale.com/eGUI right into my T Drive, where I extracted it into it's own folder on the T Drive.

7. I plugged the TWR-LCD into the Primary TWR-ELEV. which already had the K60 and the TWR-SER plugged into it.

8. On the underside of my K60 it has both of these stickers, 700-26548 REV B, and SCH-26548 REV D. Which I am assuming that the Schematic Rev is the one that I am checking to make sure is Rev. D.

9. I on the top of my board, I made sure that J16 was not jumpered.

10. First when I opened CW10.1, I made a new workspace on my T Drive. Then immediately did a reset perspectives. Afterwards I did a file/Import/Existing Files into Workplace => Then searched for T:/Freescale_embedded_GUI_SW/_Official_Demos/EGUI_D4D_Demo/TWR_K60N512/BareMetal/CW_10_1 and hit OK. made sure that the check box was checked, and hit finish.

11. Opened up d4d_user_cfg.h in Sources/project/D4D_Configuration and this is what I have now.

Line 89: //#define D4D_LLD_LCD_HW d4dlcdhw_kinetis_spi
Line 90: #define D4D_LLD_LCD_HW d4dlcdhw_flexbus_16b

12. I then hit build, which everything compiled.

13. I then switched from Internal RAM to Internal Flash, then re built the project.

13. I plugged my first usb cable into J5 on the Primary TWR-ELEV.

14. I plugged my second usb cable into J13 on the TWR-K60N512

15. I then hit Debug, which I choose TWR_K60_MK60N512VD100_INTERNAL_FLASH_PnE U-MultiLink, click OK and wait until the Resume Button at the top of the Debug window becomes available to click.

16. Click Resume, and my TWR_LCD continues to stay White. Nothing ever changes on there.... No noise, nothing.

17. I went back and tried to reverse the two define lines, to make sure that I didn't misread what was written in the other thread. I commented out the Flexbus line, and uncommented the Spi line, which they now look like the follow.

Line 89: #define D4D_LLD_LCD_HW d4dlcdhw_kinetis_spi
Line 90: //#define D4D_LLD_LCD_HW d4dlcdhw_flexbus_16b

18. I build the project again, then I hit debug and wait for the Resume Button to become available to click again. Which gives me the same exact result.

https://community.nxp.com/discussions/57-IMG_20120201_163729.jpg" target="_self

So guys... Am I doing something wrong? I am completely stumped....
