iMX8M: Copy from eMMC to TCML

[bharatkumarbach]

I understand from the documentation that Boot ROM initially loads 4K region starting from 0x8400 in eMMC to TCML and starts executing the code. I am writing a boot loader which exceeds 4K size. 

Is there any possibility that I can make Boot ROM copy remaining code?

Or should I include eMMC driver in the first 4K region and make it fetch remaining code for me?

Thanks,

Bharat

Hi Bharat

boot ROM uses ivt for loading custom application as described in

Figure 6-18. Image Vector Table i.MX8MDQ Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMX8MDQLQRM.pdf

In general yes, recommended way is to implement eMMC custom

driver in small OCRAM region and make it fetch remaining code for custom application.

Best regards
