New ContributorSoC u-boot stuck in loop trying to load bad FPGA soc
When booting SoC platform from eMMC flash device (boot-ROM --> u-boot --> linux) and incorrect FPGA image mistakenly written to eMMC the only repair option appears to be a complete flash image (sdimage) re-write. For eMMC flash device the only supported option is to change HW boot-select (BSEL) pins to cause boot-ROM to ignore flash 2nd-stage boot loader (u-boot). Then one can use Intel flash_programmer Python-script to re-write original sdimage to eMMC flash as a recovery option.
Short answer: don't mistakenly write wrong FPGA image onto MMC flash of Soc platform or you're *DEADBEEF*
New ContributorI have verified board is good by loading good FPGA soc with Quartus programmer successfully. But, I cannot save this soc into specific eMMC sectors via Quartus. u-boot and Linux images are good on flash, only FPGA soc is bad image. What tools can help me edit eMMC image without u-boot command interface?
