Regular ContributorHi,
Can you share how did you compile your U-boot and Kernel ?
Also, Is there any different from the steps from the Building Bootloader? If so, please state what is the different steps made:
https://rocketboards.org/foswiki/Documentation/BuildingBootloader#Agilex_45_Boot_from_SD_Card
Additionally, how actually did you reduce the memory and got it to boot up?, (from where, in what environment etc.) when you mentioned "If I reduce the amount of memory available to Linux (passing in up to 'mem=3584M') then the new boards boot as expected."?
Lastly, can you share the success boot logs?
Is there any different when you boot the "AGFB014R24A2E2VR0 Agilex parts" vs a success booting the "new boards with the AGFB014R24B2E3V" when reduce the memory available to Linux?
Or if possible, you can share both success logs here.
New ContributorHi,
Yes, there are differences in the steps.
- The ATF steps are skipped
- Buildroot is used to build everything, so toolchain, u-boot, linux, etc
- the steps for building the SD card image are also different. Our image is created using the genimage tool
The memory was reduced by adding the 'mem=3584M' to the u-boot bootargs that get passed to Linux.
I will add the boot log for the AGFB014R24A2E2VR0 board at a later date as I don't have that on hand.
I've attached the boot log for the AGFB014R24B2E3V board booting successfully with reduced memory.
Thanks!
New ContributorHi,
I've attached the boot log for the AGFB014R24A2E2VR0 board booting successfully with reduced memory.
The build dates are different, since I had to regenerate the .jic for the QSPI, and the eMMC image had been rebuilt with some unrelated file changes in the rootFS. The U-boot and kernel settings were unchanged.
Thanks!
