XHRA QSPI timing issue

Postby leogrimm » Fri Aug 18, 2017 2:24 pm

HI,

I got a problem which is the same as the topic described at http://www.xcore.com/viewtopic.php?f=26&t=4742

I have read the official advisory at https://www.xmos.com/download/private/D ... 1.0%29.pdf

However, the part number of my chip is "GT164901".

Is it normal? I just made a copy of the "xCORE-AUDIO Hi-Res DAC/HPA Platform" for reference purpose.

What is your datecode on the IC? Can you not return to XMOS and swap out for the proper OTP version?

PB4K30.00

That's all.

Sorry for my poor English but I'm confused about "can you not ..."
Do you mean if I can program the XMOS chip?

Hi.

Can you return the defective chip(s) to XMOS? You should be able to do this. Best to email them directly to request assistance with the OTP bug.

Thank you and I thought you were one of them.
