AM625: Booting AM625 Custom Board with different options.

Abhishek Lakhara

Part Number: AM625

Hi Ti,

We are currently working on the custom board based on the AM625 and I have some queries regarding booting the board with different options.

1) is it mandatory to do USB DFU mode to get the u-boot prompt?

2) How can we do a USB host boot? Do we need to change dts file of u-boot or kernel?

3) How to do booting over ethernet?

4) Is it mandatory to do DFU boot to flash EMMC or any other way to flash EMMC directly?

Regards,

No. Any boot mode should get you to the U-Boot prompt.

USB host boot is not currently supported in the Processor SDK.

Hi Abhishek,

In general, you can flash eMMC in U-Boot or Linux.

If you tell me what boot mode you use, I can provide details if you need it.

Hi bin liu,

We are preparing the custom board based on AM625 and I finding an easy way of flashing for mass production.

Currently, I am flashing using DFU boot.

Hi bin liu,

I can flash the EMMC using DFU but I am looking for an easy way to flash EMMC as we are going for mass production and for that is there any way like using JTAG or something else, we can flash the EMMC?

Regards,

Abhishek

Hi Abhishek,

I am not sure how JTAG would be easier than DFU for eMMC flashing. But our JTAG expert is out of office this week, I can get his comments about JTAG flashing next week.

Hi bin liu,

Thanks for your reply. I have just taken JTAG as an example. I am just looking for the easiest way for EMMC flashing else DFU booting is good for us.

Can you please explain what inconvenience that DFU flashing has?
