Hello folks u2013
I posted this question on Xilinx website but have not heard anything so far - so I'm reaching out to the collective knowledge of Zedboard community for some guidance.
I developed a custom Zynq board (using Z-7020) that includes both QSPI Flash and SD memory. It is very similar to MicroZed - however due to the use of dual USBs - microSD card is attached to SDIO-1 port. I know from Zynq TRM that only SDIO-0 (not SDIO-1) could be used for first stage booting.
My question is have you guys managed to boot Linux image (image.ub for Petalinux) from SDIO-1 after loading the FSBL/bitstream/U-Boot from QSPI Flash?
In my case u2013 I managed to boot FSBL/Bitstream and U-Boot from QSPI Flash u2013 but when I do u201Crun sdbootu201D in U-Boot u2013 the system hangs up and never responds. I monitored the SDIO signals with a o-scope but there is nothing. Any feedback/guidance is appreciated.
