Other Parts Discussed in Thread: TMDSHSECDOCK
Tool/software:
Hello all,
First of all, I think that is important for you to know:
The hardware I'm using:
- F29H85X-SOM-EVM MCU114E1-002
- All the ADC Vref switches position are UP.
- MCU134A Adapter
- XDS110 Debugger
- TMDSHSECDOCK rev F
And I did the modifications recommended on the user guide:
- Incorrect voltage on VREFHIAB and VREFHICDE pins when external VREF mode is selected
...
Now that being said, I just discovered something weird by trying to read the some ADC ports. For example when I try to read A6 or A7, and then connect those pins (equivalent to 25 an 27) on the docking station to a function generator that is supplying 1 volt.
I cannot read the right values. however if I connect the docking station pin 15 (equivalent to A9), both pins start reading some values different to 0.
My method of validate this without my code modifications was opening the sample project adc_ex2_soc_epwm and doing the following modifications to the syscfg project.

And of course commenting out this annoying STOP on the main function:
Being fully honest this is just one thing on the ADCA I detected, but there could be also more like this on the ADCC and ADCD. I'll keep you posted on this post.
So my best guess is that something might be wrong with my hardware configuration so I just wanted to double check with you here.
Thanks,
Martin
P.S. So a correction here, it seems that I screw over when I did the mapping of the F29H85X-SOM-EVM to the MCU134A. A6 is in the pin 15 and A7 is in the 17. So that explain why A6 is changing when I inject a signal on the pin 15 but why it also change A7.
