HI igorpadykov:

I have read the document, and porting android8.1.3 to mx8mq. There are two files needed to build the uboot and ddr_test_tool: bl31.bin signed_hdmi_imx8m.bin(and some other bin files : lpddr4_pmu_train_1d_dmem.bin for example).

As we are going to DDR4 not LPDDR4, my questions are:

1. do I need to rebuild bl31.bin ? There is a patch for LPDDR4 to build bl31.bin, but no patch for DDR4, and the patch could not be used in uboot of android8.1.3

2. do I need to rebuild signed_hdmi_imx8m.bin ? how to build it if needed ?

Best regards.

I do not think that *hdmi_imx8m.bin should be rebuilt.
