I prefer you write "Get firmware-imx package" instead because this is the real package name and it contains not only DDR related firmware.
ok
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.

Here you use the ATF from imx_4.19.35_1.1.0.

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?
There is no change to DDR firmware during these release. I could change to 8.5.
Regards, Peng.
Please clarfify.
Thanks
