Original question:
CC2640R2F: sdk_5_30_00_03 SimplePeripheral OAD ONCHIP SPI_Open(SPI0) returns null.
Hi
I was able to customize OAD OFF chip application for my flash chip.
OAD off chip transfer fails due to CRC error status 0x01.
Attached is the screenshot for btool.
I tested same with launchpad and everything works fine. What could go wrong with my custom board?

Hi Laskhmi,
If the same image and procedure works on an LaunchPad, but not on your custom software, then this points to a possible board design issue. Have you had your design reviewed by SIMPLELINK-2-4GHZ-DESIGN-REVIEWS? If not, then I would highly recommend you submit a request as they will provide you feedback on your design. I would also recommend reference the CC13xx/CC26xx Hardware Configuration and PCB Design Considerations and Crystal Oscillator and Crystal Selection for the CC26xx and CC13xx Family of Wireless MCUs.
The CRC Error Statuses can be found in the oad.h file:
Seems that the error is indicating that the downloaded image's CRC does not match with the expected CRC. To be safe, can you try mass erasing the external flash, the CC2640R2, and reflashing everything from scratch? Its possible there is some sort of corruption in the downloaded image or the image currently on the board.
Best Regards,
Jan
