Hi NajeemSeyed
Sorry for my very late reply, I was waiting for the latest component releases to see if they would improve the behavior.
So I reconsidered the problem from the beginning:
I finally resolved the issue on my side under following conditions :
My setup:
- Hardware : NUCLEO-U575ZI + X-NUCLEO-DRP1M1
- Tools : STM32CubeMX 6.16.0
- Software : X-CUBE-TCPP 4.2.0, X-CUBE-FREERTOS 1.2.0
I think we are experiencing the same problem because we are both working on two evaluation boards connected together by long wires.
I stabilized the behavior by shortening the wires between the NUCLEO and the X-NUCLEO-DRP1M1 and also improving the GND connection between the two boards.
- I placed the X-NUCLEO-DRP1M1 above the NUCLEO to shorten wires
- I changed the ADC channel for Ch5 to Ch7 in order to achieve a very short connection
- I ducplicated the GND connection (from SNK Connector GND to NUCLEO GND)
I attach a picture of these boards
I also attached the .ioc of my solution with the following allocated resources:
| X-NUCLEO-DRP1M1 | Signal | NUCLEO-H575ZI |
| CN7-8 | GND | CN11-8 |
| CN2-GND | GND | CN14-1 |
| CN7-16 | VDD | CN11-16 |
| CN10-23 | CC1 | CN11-17 PA15 |
| CN10-26 | CC2 | CN12-26 PB15 |
| CN10-2 | EN | CN12-29 PB5 |
| CN10-37 | FLG | CN12-40 PE8 |
| CN7-28 | VBUS | CN11-59 PG0 |
| CN10-3 | I2C2-SCL | CN11-51 PF1 |
| CN10-5 | I2C2-SDA | CN11-53 PF0 |
I tested this configuration for a while without encountering any problems.
