How to download bare code to A7

[李放.1]

 

Whether there is a bare - machine routine for MP1?

Hi,

I recall that ST is not supporting any bare solution but only Linux for A7 in its ecosystem.

Anyway, if I assume rtthread.stm32 is a bare code for A7, you can't load it into mmc0 ( SDCard) with the single line TSV I see in screenshot.

The minimal TSV might be (for a DK board ) :

#Opt	Id	Name	Type	IP	Offset	Binary
-	0x01	fsbl1-boot	Binary	none	0x0	arm-trusted-firmware/tf-a-stm32mp157c-dk2-usb.stm32
-	0x03	fip-boot	Binary	none	0x0	fip/fip-stm32mp157c-dk2-trusted.bin
P	0x04	fsbl1	Binary	mmc0	0x00004400	rtthread.stm32

This load in DDR Tf-a and U-boot enabling DFU service to flashload the fsbl1 paritition in SDCard.

Hope it help,

Olivier
