Just received a new Genesys 2 board. Flashed it and trying to boot the prebuilt version of linux from arian-sdk
Programmed the board according to here: https://reference.digilentinc.com/learn/programmable-logic/tutorials/genesys-2-programming-guide/start
The board powers up fine, copies bbl & linux image from sdcard and then no tty output. Nothing at all.
I built the sdcard using the prebuilt bbl.bin images from: https://github.com/pulp-platform/ariane-sdk/releases (I tried bbl.bin files from both 4.2 release and OpenPiton + 4.2, same result for both.)
Following instructions for creating sdcard here: https://github.com/pulp-platform/ariane-sdk
Board sees the sdcard, copies the sectors, and then nothing!
I've tried to set breakpoints at numerous places in the linux boot sequence but non of the are ever hit. Breaking in from gdb shows $pc at 0x10040 which seems wrong for linux running at 0x80000000.
Main questions are: Are the prebuilt bbl.bin images known to work? Are instructions up to date? Any suggestions on how to move forward?
Thank you!
Uart output is below. I expected to see some linux boot lines following the 'done!' message below but I get nothing.
