I'm struggling a bit getting it to actually boot; how is this supposed to be installed to the device? I've built with the two applied patches on a patched v2021.10, copying various firmware parts from: https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/bl31-iMX8MQ.bin https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/lpddr4_pmu_train_1d_dmem.bin https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/lpddr4_pmu_train_1d_imem.bin https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/lpddr4_pmu_train_2d_dmem.bin https://source.mnt.re/reform/reform-boundary-uboot/-/blob/master/lpddr4_pmu_train_2d_imem.bin export BL31=bl31-iMX8MQ.bin make imx8mq_reform2_defconfig make make flash.bin Then grepping various other README's from imx8mq devices, I tried two different processes: dd if=flash.bin of=/dev/sd[x] bs=1K seek=33 and: dd if=flash.bin of=/dev/sd[x] bs=1024 seek=33 conv=sync dd if=u-boot.itb of=/dev/sd[x] bs=1024 seek=384 conv=sync Both simply hanging with: U-Boot SPL 2021.10 (Jan 01 1970 - 00:00:01 +0000) Is the flash.bin step unecessary? I see DDR timing code in the patch series; are corresponding lpddr4*.bin no longer necessary? I also tried building with an old version of arm-trusted-firmware (v2.2), as that was the most recent upstream version that successfully built. This seems to be a fork of ATF that has support for iMX8MQ, but it is unclear which branch/tag/etc. should be used with the mnt/reform: https://source.codeaurora.org/external/imx/imx-atf It would be nice to include a board README in the next patch revision to spell out some of the details of exactly which other projects and versions/comments/branches are expected to work with MNT Reform2. I would be nice if you could CC me on future patch series revisions to be able to test.
