I’ve been working on getting linux to boot with U500 on the VC707. When I run
screen to talk to the FPGA, I get the following output:
INIT CMD0 CMD8 ACMD41 CMD58 CMD16 CMD18 LOADING BOOT INIT ...
This keeps looping, instead of ever displaying the initial SiFive logo as in the Getting Started Guide. I’m using the Vivado Lab Edition 2016.4 and the files downloaded from https://static.dev.sifive.com/freedom-u500-vc707-mcs-0-1.zip to program the device. On my SD card, I’ve built the git repository https://github.com/sifive/freedom-u-sdk.git and put the resulting bbl.bin file (~7MB).
At this point, it is hard to determine where my setup is failing, so I was wondering if it would be possible for me to download the built version of all three of these files that already work on a VC707 to try. If not, I would appreciate some guidance on where to look to debug my setup.
