OTA bootloader update_image_state(1) issue

[KyleHsieh]

I would like to update application of i.MXRT1060 EVK with OTA bootloader, but "bl_update_image_state(kSwapType_ReadyForTest)" return error as below.

And seems like the bootloader do not enter test mode after reboot. 

My steps: 

SW7 setting: 0010

1. Build and program ota_bootloader release version (using default address 0x60000000)

2. Build and program lwip_httpssrv_ota (using default address 0x60040000)

3. press SW4 to reset

4. Build the other lwip_httpssrv_ota example code and create binary for upgrade test

 

5. Use web GUI to upgrade application.

My SDK version is 3.9.3.

Thank you.

Best Regards.

Hi @jeremyzhou ,

I downloaded SDK2.10.1 and built "ota_bootloader"&"lwip_httpsrv_ota_enet" to upgrade the image.

I upgrade the "v1 image" to "v2 image" for test and works well.

But if I want to upgrade from "v2 image" to "v1 image" again.

The log will shown "Image validation failed".

What's the difference after I upgrade the image?

Thank you.

Best Regards.

Hi @jeremyzhou ,

Could you please help me to check this issue?

Do I need to sign the upgrade image if I used SDK2.10.1?

Thank you.

Best Regards.

Hi，
Thanks for your reply.
I didn't encounter the issue you mentioned, I can update the application from V1 to V2, or V2 to V1 actually.The below figure shows the update steps, and I also attached the log.

Have a great day,

Hi @jeremyzhou ,

Thanks for your help.

I tried the image that ypu uploaded.

May I ask you a few qusetions?

1. Is flash address corrected? bootloader: 0x60000000, app: 0x60040000

Which flash tools did you used?

2. What's the difference between evkmimxrt1060_lwip_httpssrv_ota_enet.bin and evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v1.bin that you upload before.

I could upload the evkmimxrt1060_lwip_httpssrv_ota_enet.bin by web GUI again and again.

But if I want to evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v1.bin update, the image would be validation failed as below.

3. Which bootloader did you used for evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v1.bin? I could not update the image even if use the same image. It could not enter the test mode after I click the upload button.

Hi,
Thanks for your reply.
1) 1. Is flash address corrected? bootloader: 0x60000000, app: 0x60040000
-- Yes.
2) What's the difference between evkmimxrt1060_lwip_httpssrv_ota_enet.bin and evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v1.bin that you upload before.
-- Actually, the evkmimxrt1060_lwip_httpssrv_ota_enet.bin is the evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v2.bin.
3) Which bootloader did you used for evkmimxrt1060_lwip_httpssrv_ota_freertos_mcuxpresso v1.bin?
-- ota_bootloader demo.

Have a great day,

Hi @jeremyzhou ,

I summary my test steps and upload my binary files on https://community.nxp.com/t5/i-MX-RT/OTA-bootloader-Image-validation-failed-issue/m-p/1506488#M21082

Could you please help us to check "Image validation failed" issue?

Hi @jeremyzhou ,

Thank you for your reply.

I referenced https://www.nxpic.org.cn/module/forum/thread-620190-1-1.html and do the test step by step.

But seems like I encouter the same issue on SDK2.7.0 and SDK2.9.3.

Do I need to modify any source or configs except for add log to test it on RT1060 EVK?

Could you build a test image include bootloader and application that I can test on my side?

Thank you.

Best Regards.

Dear @jeremyzhou ,

The attachments works well on my side.

May I ask which SDK version and IDE did you used? 

Is there anything else that I should pay attention to download SDK package?

Thank you.

Best Regards.

Hi @jeremyzhou ,

If would like to use blhost command to flash image to app area by uart baudrate 115200 as below,

blhost.exe -t 50000 -p COM11,115200 -j -- get-property 1 0
blhost.exe -t 50000 -p COM11,115200 -j -- flash-erase-region 0x60040000 0x200000 9
blhost.exe -t 50000 -p COM11,115200 -j -- write-memory 0x60040000 test.bin

How could I config ota_bootloader code for higher baudrate?

Thank you.

Kyle

[jeremyzhou]

Hi，
Thanks for your reply.
The speed argument is available to set other values than the 115200, however, the speed argument should keep the same once executing the blhost command.

Have a great day,

Hi @jeremyzhou ,

I reset and tried to used baudrate "230400" for test but get no reponse received.

Is there any max baudrate limit for this blhost?

How could I define the fix baudrate?

Thank you.

Best Regards.

Kyle

[jeremyzhou]

Hi @KyleHsieh ，
Thanks for your reply.
In my opinion, the issue mainly relates to the evkmimxrt1060_ota_bootloader, in the demo, it uses the autobaud_get_rate function to calculate the baud rate according to received data, if the calculated baud rate is far from the real baud rate, which will cause the phenomenon you encountered.

Hi @jeremyzhou ,

Thanks for your support.

Is there any way to config the higher baudrate for blhost firmware upgrade?

Thank you.

[jeremyzhou]

Hi,
Thanks for your reply.
1) Is there anyway to config the higher baud rate for blhost firmware upgrade?
- Yes, I think so, however, it needs the developer to adjust or optimize the source code.
