Occasional ContributorArria 10: Booting U-Boot from SD-Card does not configure FPGA
Hi @aikeu,
okay, now im sure: The Intel In-System Sources and Probes IP hinders the FPGA from starting normally after it has been correctly configured by SD-Card. Even the old Quartus-Project works without the ISSP-IP. Now it makes sense why the FPGA starts when a connection to the programmer is established via JTAG or similar.
My workaround will be, that i only use FPGA Firmware without the debugging features (ISSP, SignalTap, ...) on the SD-Card and when i need this debugging features i will start the HPS with the ARMD DS debugger.
Thanks for the help, my problem has been solved.

LFrin
Occasional ContributorThe problem also exists when I work without "HPS early release of HPS IO". I convert the *.rbf file with the attached script and create my SD-Card as usual. The process hangs at "FPGA: Start to program peripheral/full bitstream ...".
I also found that it is enough to connect the ARM DS debugger, stop the ARM and reset it so that the FPGA is configured correctly.
The ARM loads from the SD-Card: SPL and U-Boot load correctly, FPGA is not configured. I connect to the ARM DS debugger and run the following script:
# initialize system
stop
wait 5s
reset
stop
wait 5s
FPGA is configured correctly.
Regular ContributorHi LFrin,
Can check if the below has been enabled for your early IO release build?
To follow the new build flow referring to Appendix - Reducing Arria 10 Fabric Configuration Time ( https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10#Appendix_45_Reducing_Arria_10_Fabric_Configuration_Time ), the below items should be checked.
Thanks.
Regards,
Aik Eu
