Hi Peng,

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.

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?

Please clarfify.

Thanks

Also, in the Yocto recipe the "firmware-imx-8.5" version is also used:

You mean the imx-atf source directory ?

There is no change to DDR firmware during these release.
I could change to 8.5.

No. bl31.bin needs to be copied to U-Boot srctree dir.
