Reinstall Pemicro MSD bootloader after mbed bootloader

kirkg — Mon, 17 Nov 2014 19:39:54 GMT

When I first got my frdm-kl25z board I was able to load the .srec files from the quick start zip file. Since then I installed the mbed bootloader and have been successfully using that as well. I'd now like to go back to the pemicro loader so I can try out coding using KDS, but I'm running into problems. Here is what I have done:

1) reboot board to bootloader

2) Drag "BOOTUPDATEAPP_Pemicro_v111.SDA" into msd

3) reboot board again (this time it comes up in bootloader)

4) Drag "MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA" into msd

5) reboot board again

6) trying to drag ANY srec onto MSD

The small green led flashes, but the program never takes. Readind the text file in the MSD says "Error 7"

Any ideas on how to get back? I can put the mbed bootloader back on and everything works as it did before, I just can't get the KDS srec version to work again. Thanks

Between step 3 and 4 you need to press reset to enter bootloader mode again, see

http://mcuoneclipse.com/2014/11/01/illustrated-step-by-step-instructions-updating-the-freescale-freedom-board-firmware/

And step 2) is only needed if you need to update the bootloader (this is needed only once).

Erich,

Thanks for the reply. I'm following that instruction set you listed, but the result is the same. After the final reboot (unplug/plug) the device shows up an MSD with name FRDM-KL25Z. If I read LastStat.txt is says "Ready" and the green LED is solid. If I then drag an srec file onto it the green light starts blinking (it looks like 7-8 pulses then pauses and repeats) and the the LASTSTAT.txt file reads "Error 7". It's almost like there is something about the last mbed application on the flash it doesn't like and can't write over.

Also if I put the mbed bootloader back on, the last mbed .bin file (mbed program) I wrote to it is still there and functioning correctly, showing the pemicro bootloader isn't altering the flash contents at all.

Hi Kirk,

Are you sure you load an S19 file? Can you open that file in a text editor and check.

I have attached for you an S19 file you can try.

Hi Kirk,

I also do a test with FRDM-KL25Z board, everything is ok on my site.

I am using attached MBED FRDM-KL25Z board image, and it could works.

After that, I hold FRDM-KL25Z board reset button and enter into BOOTLOADER, then load attached [MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA] firmware.

Then, it will be recognized as [FRDM-KL25Z] MSD disc and load attached application [blinky_green.srec] image, which will run as expected.

Wish it helps.
best regards

Ma Hui,

Thanks for the response. I tried your files, but got the same result, I'm thinking something on my board is damaged. The process I went through was:

1) unplug board

2) hold reset button and plug in. Note that device shows up as MSD called Bootloader

3) Copy the MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA onto the drive. LASTSTAT.txt says complete

4) unplug board, replug board. Now MSD shows up as FRDM-KL25Z

5) drag blinky_green.srec into folder. Small green LED starts to blink rapidly in pulse groupings of 7 (I think it's 7, but they are fast). Reading LASTSTAT.txt after loading srec says "Error 7"

6) plug/unplug board no change.

7) pound head against wall....

8) unplug board, hold reset, plug in board. Opens as MSD called bootloader.

9) drag mbed bootlaoder back on.

10) unplug/plug in board

11) previously installed mbed app still on and functioning as before.

12) try dragging new mbed app on. This works too.

Thanks

Kirk

Erich,

I tried using your file, but got different results:

1) unplug board, hold rest, plug in board

2) Board comes up as MSD bootloader

3) drag Freedom_LED.s19 into folder

4) unplug/plug in board. Board comes back up again as bootloader even though I didn't hold reset

5) repeast step 4 with same result

6) try dragging MSD-DEBUG-FRDM-KL25Z_Pemicro_v114.SDA (latest Pemicro firmware from their web site)

7) same results as before.

The 2 bootloader files I'm trying to ge between (pemicro/mbed) are NOT ascii s19 files, but binary SDA files. Thanks

I have seen cases were virus scanners have a bad impact. Can you disable it and try it without virus scanner active?

Another option: use the DOS/cmd prompt to copy the file to the FRDM-KL25Z drive

Hi Kirk,

the process to load the S19 file I have sent you is:

- power the board normally. It should come up as FRDM-KL25Z drive

- copy the S19 file to the board

this will program the file and run it (blinking LEDs').

What is shown if you opent he .htm file on the FRDM-KL25Z drive? It should show you the firmware version/etc.

Erich,

Ok, I will try that this afternoon and send several screen shots. So the only difference here is that this is an Ascii s19 file instead of an Ascii srec file correct? What is different about this file, or is this just one more test case? Thanks

Kirk

The extension does not matter.

s19 == srec

Erich,

Thanks I will try that as well, but is there any reason to believe the virus scanner would act differently between the mbed bootloader and the pemicro bootloader?

Kirk

Re: Reinstall Pemicro MSD bootloader after mbed bootloader

BlackNight — Tue, 18 Nov 2014 17:25:00 GMT

that might depend on the virus scanner I think. Just wanted to throw in a different angle.

Erich,

One more point of information is that when I first got the board, and before installing mbed, I was able to successfully drag/drop the precompiled example srec files into the pemicro boot loader. The problems have all been related to trying to get back tontine starting state. Thanks again

The best I can tell from the "Error 7" and the Console debug message I get from KDS is that with the PEMicro bootloader the board is "Unable to enter background mode". Does this help or tell you anything? Thanks

Kirk

BlackNight — Wed, 19 Nov 2014 06:44:28 GMT

That looks all ok.

Intererestingly, I have a MicroBoot Kernel Version is: 1.01

Probably because my board is an older one.

Erich

BlackNight — Wed, 19 Nov 2014 06:45:47 GMT

To me this "unable to enter background mode" says that it cannot halt the KL25Z so it can be debugged with the OpenSDA.

So the K20 is not able to take control over the KL25Z.
