AM4372: Using Uniflash to program QSPI memory

The software team have been notified. They will respond here.

Hi Biser-san,

What's the status now?

Feedback will be posted directly here when available.

Hi RonB-san,

Thank you for your reply.

I need to use Windows host.

This is TI EVM(TMDXSK437X).

SDK version is PROCESSOR-SDK-LINUX-RT-AM437X _03_03_00_04.

By the way, now it is the phase that customers are investigating AM 437x, so I am using TIEVM.

In the mass production phase, customers need to write to SFLASH with Uniflash on custom boards.

Best regards,

Sasaki

Hi,

Could you teach me how to program TMDXSK 437X's serial flash using Uniflash?

Best regards,

Sasaki

Sasaki-san,

Yes, I will be glad to help you. I'm looking at improving the documentation, which is quite out of date. It will take me a couple of days to do so.

Are you planning to use the AM437x Starterkit EVM? This is the board that has QSPI flash on it, and can boot over USB. This is what I plan to use for my update.

RonB-san,

Thank you for your support !

Yes, I'm using AM437x Starterkit EVM.

Please let me know when updating the document.:)

Sasaki

Sasaki-san,

I've updated:

processors.wiki.ti.com/.../Sitara_Uniflash_Quick_Start_Guide

It should now have accurate instruction to allow you to set up Uniflash to talk to the AM437x SK.

The current SDK U-Boot supports booting from USB using the am43xx_evm_usbspl_defconfig. Building with this config, renaming the files, and copying them to the Uniflash computer should allow you to boot to a U-Boot prompt over USB.

You should be able to use the information here:

processors.wiki.ti.com/.../Linux_Core_U-Boot_User's_Guide

to complete the flashing process. Once everything is working, you can then translate those commands into a debrick.scr file that can be reused.

RonB-san,

Thank you for your special support !

I have a question to read it.

The following "opendhcp.cfg" does not exist in my folder.

I have Uniflash v3.1, v3.3 and v3.4, but that file is not in any uniflash folder.

Which folder is the file?

Best regards,

Sasaki

Sasaki-san,

Sorry about that. You will probably need to create a configuration in Uniflash before this file is written the first time. You may even need to start a flashing process. Could you try these two to see if that creates the file, so that you can then edit it?

RonB-san,

Thank you ! I will try it with reference to your advice.
