Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Fri, 27 Apr 2018 17:25:28 GMT

I purchased a FRDM-KEAZ128Q80 from DigiKey. The OpenSDA portion of the board appears to be nonfunctional. The demos work if I connect a 12V source, but connecting a USB cable doesn't power the board or enumerate with a computer. When connected only to USB, I can probe that power is getting to the OpenSDA MCU, but the main power busses are not on. Is my board just defective, or am I missing something obvious?

Hello Adam,

I've had a lot of issues with FRDM boards initially. Some bootloaders (like DEBUG-APP_Pemicro_v102.SDA) do not enumerate the board on connection to USB. Also some boards do not come with the example application burned, hence the only LED that will light up is the OpenSDA LED.

Therefore, a) make sure that you have the correct bootloader burned. b) make sure you're using the SDA onboard USB port. c) How exactly did you measure the "main power busses"?

Hi Adam,

Please check J107 on your board, you need to connect pin2,3.

If you just connect the USB cable, whether your D2 is lighting or not?

Please also tell me what the PC operation system you are using?

Have a great day,
Kerry

Mahmoud,

Thanks for your help. This is my first foray into the world of Cortex and NXP KE, so my apologies if I'm missing some thing straightforward. I was under the impression that the secondary microcontroller attached on the circuit board, the one connected to USB, was pre-burned with firmware to act as a programmer/debugger for the main microcontroller, the KEA128.

Since my original post, I've received a second replacement board from DigiKey, and it acts the same way. In both cases, the demo application on the KEA128 appears to work properly when connected to an external power supply, but the programmer/debugger and USB interface seem to be nonfunctional.

a. How can I verify the bootloader? I was expecting that the board would appear as a mass storage device and serial port out of the box. Currently, none of the LEDs light up at all when connected to USB, including the OpenSDA LED.

b. My board only has a single microUSB connector, and I'm connecting to that one.

c. I probed a few test points on the board to see if the USB connector was bad. P5V_SDA and P3V3_SDA have power, but P5V0 and P3V3 do not.

Kerry,

The J107 jumper is connected to 2-3, I did try 1-2 also. None of the LEDs on the boards come on when they are connected via USB. For host devices, I've tried Windows 10, Windows 7, MacOS, and connecting directly to a USB phone charger.

OK I'm sorry, I completely overlooked the board that you are using.

a. In order to enter OpenSDA bootloader mode: unplug the USB cable, hold the reset switch and plug into USB again. If you have the drivers installed, it should show up as a removable storage in file explorer. Open SDA_INFO.HTML to check the status of your bootloader (version etc.). Anyway I think this should work since you say P5V_SDA and P3V3_SDA have power.

VOUT (pin 6 of MIC2005) is the source of power which the "really important" jumper J107 feeds from.

In order to enable this chip, it either needs POWER_EN (logic signal coming from OpenSDA interface) or R70 to be populated. The default scenario is that R70 is not populated (DNP) and that OpenSDA enables power. That's why I wanted you to try a different bootloader, maybe it was a bad batch they received at Digikey.

So after you double check that J107 connects (2 and 3), please compare your board to the above schematic and report back.

Hi Adam,

Now, please follow my step to test the board again, please use the win7 system to test it at first.

1. Download the according software

1) Download Pemicro driver and install it from this link:

http://www.pemicro.com/downloads/download_file.cfm?download_id=53

2) Download the firmware

http://www.pemicro.com/downloads/download_file.cfm?download_id=378

Unzip it, find file:MSD-DEBUG-FRDMP-KEAZ128Q80_Pemicro_v118.SDA , this is the opensda firmware, will be used.

2. Change the on board bootloader to opensda

1) Power off the board, then press the on board reset button, hold on it, plug the USB cable to J7, release the button

You will find your PC have a device named as "BOOTLOADER"

2) Send file MSD-DEBUG-FRDMP-KEAZ128Q80_Pemicro_v118.SDA to your "BOOTLOADER", and wait the sending finished.

3) Unplug the USB and plug the USB cable again

You will find your board is a device named as "FRDMPKEA128", just like this picture:

Until now, your on board bootloader is changed to the opensda, you may also find the com port in the device manager:

3. Download the KEA app code to your MSD board.

FRDMPKEA128 is also a MSD device, you can send the KEA app to this device directly.

Please check my attached Lab1_Blinky_Loop_KEA128.srec, this code will blinking the D11

Unzip my attached code, then send Lab1_Blinky_Loop_KEA128.srec to your FRDMPKEA128 .

The following picture is my test result":

Please follow my above steps try it on your side carefully.

Besides, If it works, you can updated your bootloader to the latest version, just follow these step:

Issue: Bootloader versions 1.10 and earlier are not allowing firmware update and MSD FLASH programming on my OpenSDA board, with the Linux, MacOS or Windows 8/8.1 operating systems.

Solution: Support for Windows 8/8.1, MacOS and Linux operating systems was added to Bootloader version 1.11 and MSD firmware version 1.14. Please make sure that your board is programmed with Bootloader version 1.11 or higher prior to attempting to update your OpenSDA board with a new firmware application.

Important: If you are currently running Bootloader version 1.10 or earlier, you will need to find a Windows XP or Windows 7 PC to perform this update.

Please follow these steps to find out what version of Bootloader your board is programmed with:

Start your board in Bootloader mode by holding down the RESET button prior to plugging it into USB port.
Open the SDA_INFO.HTM file, which will contain version numbers of Bootloader as well name and version of current OpenSDA firmware you are using. If your board is not running Bootloader version 1.11 or higher, please download the latest OpenSDA Firmware Apps from P&E website and follow instructions in corresponding documentation to update the Bootloader using the BOOTUPDATEAPP_Pemicro_v111.SDA application. Once the Bootloader is updated via BOOTUPDATEAPP, the OpenSDA board can then be upgraded to the latest combined MSD/DEBUG OpenSDA firmware 1.14 or greater.

Wish it helps you!

Have a great day,
Kerry

Kerry,

I followed your instructions and installed the drivers on Windows 7, however, neither board appears as a device after reset. Nothing shows up in Device Manager, and there are no new drives that appear. Here's a video--you can see that there are no LEDs on at all when connected via USB.

https://drive.google.com/file/d/11OEOkk-AXcoV-C5sa_Y-b12mdOltZTeQ/view?usp=sharing

I suspect the programming/debugging firmware was never loaded on these boards. Would that make sense, and, if so, is there a way to program them without additional hardware?

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Thu, 03 May 2018 17:58:43 GMT

Mahmoud,

The board doesn't appear at all when I hold down RESET and connect it to the computer. R70 is not populated on my board. Using a DMM I see that U11 has a 5V supply on pin 1, but POWER_EN is driven to 0V.

When I connect a 12V supply and move J107 to connect 1-2, both boards run the demo code. If the jumper is in 2-3, D1 and D3 come on:

here's a video of board running demo code (only works w/ 12V power connected):

kerryzhou — Fri, 04 May 2018 02:03:22 GMT

Hi Adam Johnson

I highly suggest you follow my step to change the on board bootloader at first, because I find the POWER_EN is controlled by the MK20DX128VFM5:

So, try to change the bootloader in my last reply, at least it works on my side.

Besides, my FRDM-KEA128 board version is REV B, do you use the same version?

Have a great day,
Kerry

adamjohnson — Fri, 04 May 2018 15:28:25 GMT

Kerry,

I tried following your instructions step by step. When I hold down Reset and plug in the USB cable, the BOOTLOADER drive doesn’t show up. Nothing happens at all. Therefore, I can’t change the Bootloader. Is there another way to change it? Alternately, will NXP exchange these for functioning boards? Thanks for your help.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Fri, 04 May 2018 15:29:27 GMT

Also, my boards are revision B1.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

kerryzhou — Mon, 07 May 2018 02:28:56 GMT

Hi Adam,

Do you install the P&E driver in win7?

When you first plug the board, you need to wait a moment, because the PC need to install it, run the driver automatically.

So when your enter bootloader mode, can you find any USB device is installing?

Please also check the PC device manager, this is my situation:

You can also post your according picture.

Have a great day,
Kerry

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

kerryzhou — Mon, 07 May 2018 02:31:50 GMT

Please also check J104, you need to connect pin 1,2, NOT 2,3.

Have a great day,
Kerry

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Mon, 07 May 2018 22:56:42 GMT

Kerry,

I did install the P&E driver in windows 7 per your instructions. As you can see in my video from above,(https://drive.google.com/file/d/11OEOkk-AXcoV-C5sa_Y-b12mdOltZTeQ/view?usp=sharing) nothing appears in Device Manager when I hold down reset and plug in either board. I have J107 set to 2-3 and J104 set to 1-2.

Is there another way to load the bootloader onto the boards? If not, can you exchange them for working ones? Thank you for your time.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

kerryzhou — Wed, 09 May 2018 02:00:39 GMT

Hi Adam,

Thank you for your updated information.

From your video, it seems your board really have the problem.

Please use DMM test these points just with USB cable plug in:

1. P5V_SDA, from your previous reply, you already have 5V, please double check it with USB cable plug in.

2. SDA_VOUT33

Please test the J9, do you have the 3.3V output?

3. Test POWER_EN

4. Please check D2

it seems your D2 didn't blinking.

After you test it, please give me reply.

In the meanwhile, I will contact with our according department, check whether there any difference between FRDM-KEA128 revB and revB1, because I just have rev B on my side.

Any updated information on my side, I will also let you know.

Have a great day,
Kerry

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Thu, 10 May 2018 02:31:24 GMT

Hey Kerry,

I re-checked these measurements on both boards while connected only to USB:

P5V_SDA measured at L1 shows 5 V

SDA_VOUT33 measured at J9 shows 3.3V

POWER_EN measured at R69 shows 0V.

Let me know what you think about this....I've ordered another board, this time from Mouser. I'm going to see if I get different results from that one.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

kerryzhou — Fri, 11 May 2018 02:03:57 GMT

Hi Adam,

Thank you for your test result.

From your test result, the problem still in the on board K20 chip side, it seems the on board K20 program didn't work, because you even can't enter in the BOOTLOADER mode, don't worry, I already check it with our according department, I am also waiting for the response now, because I don't have the rev B1 board like you, then I also buy a new board, and waiting for the new board now, just want to check, whether all the rev B1 have this problem.

After you get the new board from Mouser, please test it with WIN7 system at first, don't use win10. Then tell me the test result.

Any updated information on my side, I will let you know ASAP, please keep patient, thanks a lot for your understanding. And sorry for the inconvenience we bring you.

Have a great day,
Kerry

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Tue, 15 May 2018 00:06:13 GMT

Kerry,

I received the board from Mouser, and it has the same issue as the other two. Demo works fine from the 12V supply, but plugging in the USB cable does nothing. I only attached this to a Windows 7 machine that already had the drivers on it. This one is a rev b, not b1. I'm attaching photos of the labels from all three boards. Tried several different microUSB cables and several PCs (and Macs) at this point. I feel like I'm missing something obvious, but it's not clear what it is. Let me know what the next step is.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

adamjohnson — Tue, 15 May 2018 00:07:56 GMT

Also, I'm open to shipping one or all of my boards to you for analysis, if we need to do that.

Re: Problem with USB/OpenSDA interface on FRDM-KEAZ128

kerryzhou — Tue, 15 May 2018 02:02:56 GMT

Hi Adam,

Thank you for your updated information, that's strange with rev B, because rev B works Ok on my side.

Now, please try to enter the bootloader again with your revB board.

Please note, power off the board, then hold on the reset button, hold on it, plug the usb cable, don't release the reset button, wait about 10 seconds without release the reset button, then check the PC , can you find the BOOTLOADER device or not?

Please also check your device manager, whether there has the new USB controllers?

Please try it now.

I also think it may have some other problems, if revB also have problems on your side.

Besides, do you install the P&E driver before? this is also important.

Any updated information please let me know.

Have a great day,
Kerry
