AM5726: AVS efuse values clarification

Michael Shklyarman

Part Number: AM5726

Champs,

uboot prints efuse values and customer noticed on one of their boards VDD_MPU[OD] < VDD_MPU[NOM] and on another VDD_GPU[OD] < VDD_GPU[NOM].

Is this a valid configuration or something's off?

thanks,

Michael

Michael,

That sounds odd to me too. Please have the customer provide the DIE_ID for each of these devices and we will pull the production data for these devices.

Michael,

Is this still an active thread? If there will be a long delay, we can close this one and open a new one when your customer is ready.

Michael,

FYI, I created a DSS script that will decode all the AVS and ABB values and print them into a table. Please have the customer download this file:

https://git.ti.com/cgit/sitara-dss-files/am57xx-dss-files/plain/am57xx-avs-abb-decode.dss

They can connect with JTAG via CCS and run the script by following the instructions here:

https://git.ti.com/cgit/sitara-dss-files/am57xx-dss-files/tree/README

The output file logs the die ID and outputs an easy to read table of all the values. It should be a good sanity check to understand whether something is going wrong in u-boot, etc.

Best regards,
Brad
