IMX8MQ6 BSDL/ID Code mismatch

[ians1]

Hello I hope someone can help!

I have a IMX8MQ6CVAHZAB populated twice on my pcba. (TDI = W5, TDO = U5).

When sniffing the device with jtaglive it reads the 'freescale' ID code as 00001000100011100010000000011101

This matches the user manual description of the SJC ID Code

However the BSDL file (IMX8M) lists the ID Code as 00011100111110000000010101010011

JTAG Mod is high, and only one core is detected.

I am also confident the other pins are as per the compliance section.

Can anyone advise if there is a different BSDL file I should be using?

Thanks Ian
