xCORE-XA with ARM core (not) flashable?

Postby aclassifier » Sat Jun 20, 2020 1:48 pm

I have brought this up in [1], but now I am starting this as a new thread.

I am stuck and don't know how to flash the code on my obsoleted xCORE-XA Core Module board. I have tried "everything".

I will try not to bring this thread to a full stop by my own, too many words, this time. But I will refer to a blog note where all I have tried is shown [2]. But the crossing pont between xTIMEcomposer and SEGGER seems to be of vital interest? (14.4.1 should support it, ..plus SEGGER..?)

[1] AN00141 "xrun: Invalid executable file passed" for xCORE-XA Core Module
[2] My processor-to-analogue audio equaliser notes (Disclaimer) - no ads, money, gifts etc.

Hi. Saw your other posts on this topic but been swamped in trying to get our SMT line operational. Too much of not fun times.

I know for sure that we have this same ARM XMOS kit in the building and recall testing with the XMOS demo IP and it worked correctly. From memory, believe that the ARM core was licensed from Silabs.

Can try to recreate the demo for similar testing but need a short summary of what you are attempting to compile / do with this board.

No promises on timeline as we need to get our SMT line operational to build some support equipment for this dreaded covid-19 virus.

This would be more than I dared hoping for! I have planned to publish the code as a zip at my blog, but for now I'll just mail it to you (tomorrow, Sunday). I may still publish it as it is.

There are three external buttons, and I2C display and an I2C AudioMUX from MikroElektronika, containing a TDA7468D audio controller. Just for fun I've put them on individual I2C lines. The thing lets me control the volume, bass and treble of the AudioMUX. That's all. Only XC code of course. So I have made more safety critical systems in my life, I admit. But I thought I should for once use one of the two xCORE-XA boards I had. I have no use for the ARM. But I did add the AN00141 application note there, but I would only need a nop in main, really.

HOWEVER, should anybody else know how to get xflash doing this, nothing is better! I assume a solution could move some more of those boards out of the cupboards?

I stand the chance here to publicly show that I have no pigeon and no hat. Fair enough.

Should you not find any xCORE-XA board I have two and could send the other to you to test on.
