SPI Chip select toggles continuously in Elkhart Lake Board

[Jayasurya]

Hi All,

We are trying to port Slim bootloader into our custom intel Atom processor card(x6212re).  As mentioned in the below website, we have created slimbootloader binary file and stitched into the IFWI image which we got from intel. Once image created successfully, we have flashed into out SPI flash using DediProg tool. After flashing we couldn't be able to see any prints in the debug Uart(UART2).

Slim bootloader Build Link: Elkhart Lake CRB Board — Slim Bootloader 1.0 documentation

To debug, we probed SPI flash Chip select and clock lines. I have attached images for your reference. As our understanding while probing, spi chip select lines are toggling continuously. Are we probing, correctly? Why we can't be able to see any prints in Uart?

Kindly help us to debug this issue and port slim bootloader in our custom board.

Thanks in Advance.

Best Regards,

Jayasurya R.
