Which file system should be used for SD card OTA update

[mark_li]

Hi,

I'm evaluating the SBL+SFW on the RT1050EVKB board, I have programmed sbl.bin and app1.bin to the flash, then from the SFW user guide chapter "7.2.2 SD card OTA", it says:

• Insert an SD card to the PC, and copy the app2.bin to the SD card.
• Rename the filename to newapp.bin.

I'm wondering how to partition the SD card and which file system should be used? I tried copying the newapp.bin to the first partition which uses FATFS, but seems the SFW firmware failed to read the new firmware, see below print from debug console:

  Card inserted.
  Hello world1.
  Hello world2.
  Hello world1.
  Hello world2.
  Hello world1.
  Hello world2.
  sd card ota task running failed.

Hi Kerry,

Sorry for the late reply, fat32 works for me, thanks for your support.

Hi @mark_li 

   sbl.bin and app1.bin are in the different flash address, so which detail address you have programmed?

   About the sdcard file system, you can format it to the fat32 at first, then copy your app.bin to the sdcard directly.

  If you still have issues, please also upload your tested abl.bin, app1.bin, and tell me your programmed address, then I will help you to test it on my side.

Best Regards,

Kerry
