I prefer you write "Get firmware-imx package" instead because this is the real package name and it contains not only DDR related firmware.
As per the "Rev. L4.19.35_1.1.0, 11/2019" i.MX Linux® Release Notes : "i.MX Firmware including firmware for VPU, DDR, EPDC, HDMI, and SDMA.
+- Build U-Boot +- Boot
+Get and Build the ARM Trusted firmware +====================================== +Note: srctree is U-Boot source directory +Get ATF from: https://source.codeaurora.org/external/imx/imx-atf +branch: imx_4.19.35_1.1.0
Here you use the ATF from imx_4.19.35_1.1.0.
+$ make PLAT=imx8mn bl31 +$ cp build/imx8mn/release/bl31.bin $(srctree)
+Get the ddr firmware +============================= +$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.0.bin
but here you use the firmware-imx-8.0 version.
According to the "Rev. L4.19.35_1.1.0, 11/2019" i.MX Linux® Release Notes the firmware-imx version in this release is "firmware-imx-8.5.bin" instead.
Shouldn't we use all the software components from the same NXP BSP release to avoid potential mismatch?
Please clarfify.
Thanks
