Hello.

I’d like to connect to i.MX27ADS by OpenOCD.

However, I’ve not succeeded yet.

advice me, plz.

log list is below

I am currently using OpenOCD with MX-21 which is very similar to MX-27

Then, I am quite sure you will access your CPU using the MX21.cfg here attached. Meanwhile, I am looking for accessing StrataFlash b OpenOCD… I believe your MX-27ADS does not have Intel STrataflash on-board

Warmest regards

Roberto

Thank you for your reply. rquisto.

I tried your configuration.

But I’ve not succeeded to access my CPU.

I think my OpenOCD found 2 jtag device on this part.

so i wrote 2 jtag device setting.

I believe your MX-27ADS does not have Intel STrataflash on-board

MX-27ADS board has SPANSION “S71WS-NX0 Based MCPs”.
