I'm facing an issue that I can't get around : In order to maintain the software on our microcontroler, I would like to be able to get the firmware version of the DSP softwares that are inside the selfboot memory.
I found out that there is an option in Sigma Studio to do that and this wiki explains how to do so :
I managed to read back the version of one of the 2 DSPs we have on our product, but the second one gives me weird data...
I read the last 4 bytes of DM1, as mentionned in the wiki :
- DSP1 (ADAU1452) 0xAFFF returns the good version number when read
- DSP2 (ADAU1451) 0x9FFF returns wrong data.
Is there something I'm missing ?
Thanks for the help,
