OpenWRT on LS1046A-RDB

rapter465 — Wed, 15 Jun 2022 20:19:41 GMT

I am currently evaluating a new LS1046A-RDB board for consideration in our next product. We are working through getting the different LSDKs loaded into QSPI and eMMC with mixed success. While we've been able to flash and boot to the Ubuntu-based LSDK, we are currently unable to flash and boot from either QSPI, eMMC, or SD Card for OpenWRT. I've tried both upstream latest stable OpenWRT (v21.02.3), as well as the Layerscape 20.09 fork. Attempting to boot either builds (as well as reference build from OpenWRT's website) results in the following error:

//////////////////////////////////////////////////////////////////

I built OpenWRT with the following menuconfig options:

./scripts/feeds update -a
./scripts/feeds install -a

make defconfig
make menuconfig
- Target System: NXP Layerscape
- Subtarget: ARMv8 64-bit based boards
- Target Profile: NXP LS1046A-RDB SD Card Boot

make -j1 V=s

Any assistance would be greatly appreciate as we work through our trade study.

Something to note, I did compare the ddr_init.c and platform_def.h files in the OpenWRT repo vs the flexbuild NXP Ubuntu repo and did confirm that the files in OpenWRT are older and have some significant changes.

Please put the attached patch in folder openwrt/package/boot/tfa-layerscape/patches, then run "make" to rebuild image.
