imx8qm lpddr4 android bsp

[Grigoriy]

Hi!

I'm trying to flash a board from phytec with imx8qm on board. I've downloaded Android 14 from the nxp page. I tried to run uuu_imx_android_flash.sh script but it keeps failing with error:

[HID(W): LIBUSB_ERROR_TIMEOUT (-7) ] SDPS: boot -f imx-boot-imx8qmmek-sd.bin-flash

The command was:

sudo ./uuu_imx_android_flash.sh -f imx8qm

As I understood the error is related to LPDDR4 and DDR4. The board has LPDDR4 and my question is the android build or uboot from the build don't support LPDDR4?

Also, tried to flash linux and got the same error.

Hi,

Thank you for your interest in NXP Semiconductor products,

The problem is the imx-boot image, there must be differences other than the LPDDR4 because 8QM-MEK has a LPDDR4 memory. The differences in RAM configuration, channels of PMIC, memories, etc. cause failures probing, then failure booting an image specially with this SoC since the resources are managed by SCFW.

You have to use PHYTEC release of Android since it requires a lot of partitions and are checksum-ed, with Linux you could adapt working with our RootFS integrating PHYTEC imx-boot, device tree and probably Kernel image, the other option is to use PHYTEC Linux release too.
