QCVS Read SPD With multiple devices in JTAG chain

[perfranck]

Going through the QCVS manual​ to tweak the settings on the DDR4 we have on our LS1020A hardware, and trying to follow the "1.2.3.1 Using Read from SPD option" section. I assume this "Read SPD" assumes the LS1020A is the only thing on the JTAG chain, like with the "Target Connections" under validation?

Which script can I edit to add any generic devices and their bypass info on the JTAG chain?

thanks

You already know the scripts (connect.py and connect_call.py).

Ah, they use the same scripts? Interesting, because I cannot get it to work. I will have to dig deeper on our end then.

Look at attached file. It is JTAG Chapter of the "CW_ARMv7_Targeting_Manual.pdf" file. This file is available in CodeWarrior folder.

Have a great day,
