Hello Daniel Shtaingus

Thank you for the query.

Please have a look at SK-AM62B-P1

Hello Sreenivasa,

I tried to find some info regarding this evaluation board and did not find any document describing the ability to boot-up from NOR flash.

Can you please be so kind as to point out some links for me, related to my issue?

Regards

Hello Daniel Shtaingus

Thank you.

Please look at the SK schematics and you see the flash mounted is a NOR flash.

Hello.

Thank you for your prompt response.

We have asked our HW team to review the SK-AM62B-P1.

Their response is: SK-AM62B-P1 has a different CPU and despite the fact that the NOR is indeed connected in the schematics,

the chip itself is “aka NOR” i.e. it supplies the common NOR interfaces. Still, it lacks real NOR capabilities,

while in our (Aitech) board it is a real NOR.

Our question is:

If there is no HW limitation to boot the AM62A from NOR, can we take SK-AM62B-P1 NOR driver as a reference and port/adapt it for our board?

If the answer is positive, could you please share the location to download it from?

No hardware limitation.

Help me understand the software development environment you want to use - Linux?

Thank you.

Let me check with internally and assign to the expert.

I will assign to the Linux expert to start with.

Hello Sreenivasa

I want to port the UBoot to NOR Flash. I'm looking for a UBoot source, that supports NOR flash.

Since you mentioned in your earlier answers the SK-AM62B-P1 board, can you please point me to the source of this board UBoot?

Hello Sreenivasa,

Thanks for the fast reply.  I'll wait for your answer.

Just wanted to point out some things.

As a first step in UBoot adaptation, I would like to see something similar to what I have.

1. The configuration file for my current source is configs/am62ax_evm_a53_defconfig

2. DTS file arch/arm/dts/k3-am62a7-sk.dts

If you can point to some similar files?

Hello Daniel,

The AM62x board supports NOR flash, you can download the Linux SDK from the following link:
