Why does Agilex™ 5 FPGA ES fails to boot from SDCard and eMMC devices in SDR104, HS400 and HS200 modes? - Why does Agilex™ 5 FPGA ES fails to boot from SDCard and eMMC devices in SDR104, HS400 and HS200 modes? Description Due to a problem that is under investigation, the Agilex™ 5 FPGA ES (Engineering sample) devices may fail to boot from SD Card in SDR104 mode and from eMMC in HS400 and HS200 modes. The failure is observed in U-Boot and Linux*. In U-Boot, the signature of the failure can be seen from instability when loading any component from the device. In Linux, the failure signature is observed from ‘ Buffer I/O Error on dev mmcblk0 ’ errors when accessing the device. Resolution At this time, there is no workaround for this problem, and it’s recommended to switch to the Agilex™ 5 FPGA Production device, in which this problem does not occur.
