bootload for k60 use by serial port

[李志權]

I have searched an2295

http://cache.freescale.com/files/microcontrollers/doc/app_note/AN2295.pdf?&Parent_nodeId=&Parent_pag...

https://community.freescale.com/docs/DOC-95039

But I only find the IAR and KEIL projects inside, had not found the cw,

Can provide a project of the cw?

Or tell me how to create the bootload projects?

I use the development board is TWR - K60D100M

The cw version is 10.4

[李志權]

Thank you, I rewriting the bootload code, and debug to ok, the problem has been solved, thank you.

[yantailuo]

How do u fix your problem? i encountered the problem as u did.

[李志權]

use FLASH_LDD module to rewrite the bootload code

But my company code is encrypted, copy not to come out to you,sorry!

[yantailuo]

i think u mean u replace all the flash erase and write operation in AN2295 with the function generated by FLASH_LDD module?

[李志權]

Yes,you right

[yantailuo]

Sorry to write a letter to trouble u, coz i didn't see u reply to me. i understand the code is encrypted,  but can u explain that why this problem happened? i mean that the memory programme is not success. thank u

Looks like you are using the legacy Freescale compiler (not the new GNU ARM gcc one).

This compiler only offers to generate an S19 file in the linker options.

I recommend that you either use GNU ARM gcc compiler in CodeWarrior, or have a look at these forum posts:

S19 vs. HEX

CW 10.2 / K70 How to create S19 or other file for Flash burn

Hello:

You can find the latest firmware package with the CodeWarrior projects if you run a search for "AN2295SW" in Freescale WebPage.

In any case I leave you here a link to download it:

Hope this helps!

I downloaded it and Try to compile it.

But compiling failure.

[Hui_Ma]

For the <bootloader_asm.s> file is bootloader jump to application function for KEIL compiler, please remove this file for CodeWarrior project compile.

And after that, customer need clear the project, please select menu "Project -> Clean..." to clear this project.

Then, customer need modify the link file address, which using the absolute address for that file, customer can modify it with below path:

${ProjDirPath}\CW_Linker_cfg\AN2295_LinkerFile.lcf

The below picture for more detailed info, after that, there with no compile issue about this project.

Wish it helps.

When I debug, also found a problem:

When I click on the Connect, there will be a timeout,just like

Using a serial port debug tool, found that it is to get the data

But in the code, it is also read in the data

so,What is the problem?

[Hui_Ma]

About how to generate S19 file, you can refer below picture for CW project:

Step 1:

Step 2:

Step 3:

I also recommend to refer below link about application link config file:

I have writed a application with a serial bootloader support for TWR-K60D100M

Wish it helps.

[李志權]

I according to your method to generate the s19 file, and the connection, but it hints

when i click AutoProgram、Read、BlankCheck ,it show

[Hui_Ma]

The application code need start address at 0x4000, customer need to modify the application project link configure file (.lcf) to set the application code start address.

Wish it helps.

[李志權]

I didn't find the LCF files in the project, but have found. Ld file

And then the start address modification into 0 x4000

But after recompile, and become the original value

[Hui_Ma]

For you are using Processor Expert tool, it need to set the Processors' Component Inspector [Build options] to set ROM/RAM Areas.

Please check below picture for more detailed info:

Wish it helps.

[李志權]

Change the address after compile successfully:

But burning program still fail:

[Hui_Ma]

I am not sure current AN2259 software supports TWR-K60D100M(Kinetis 100MHz silicon 2.x) board or not. As I know, previous AN2259 software only supports TWR-K60N512(Kinetis 100MHz silicon 1.x) board.

I will check it and let you know later.

Thank you for the patience.

[李志權]

I according to the code of AN2295, rewriting a bootload, now can download S19 file correctly.

But I can only use RAM way can jump to APP, use FLASH mode will not be able to jump to the APP

[李志權]

I want to burn AN2295, but didn't find how to generate the hex file options
