NUCLEO_F746ZG Issues

[screamerbg]

Description

• Type: Bug
• Priority: Major

---

Interrupt failures (InterruptIn)

InterruptIn on D2 actually works
InterruptIn on D3 throws greentea error, I suspect that the test crashes
InterruptIn on D4-9 are skipped due to the error with InterruptIn on D3

Analog In failures (AnalogIn)

Analog Input on A0 (fails with ARMCC, works with GCC)
Analog Input on A5 (fails with GCC, works with ARMCC)

I2C failures with EEPROM (I2C)

I2C - EEProm Write - 2bytes (but 1 byte words)
I2C - EEProm Write - 10bytes
I2C - EEProm Write - 100bytes

Target
NUCLEO_F746ZG

Toolchain:
GCC_ARM+ARM

Added I2C issues @bcostm @adustm

Note that ST Discovery F746NG based on the same silicon has issues with AnalogIn A0 only, not A5. A clue that this might be peripheral configuration issue

Hi,
I just pushed a fix for InterruptIn test.
SYSCFG_EXTICR4, EXTI_IMR, EXTI_RTSR, EXTI_FTSR registers were not in a correct state after the sw destruction of the InterruptIn object.
The next time those HW registers were activated by a new InterruptIn object, the interrupt management was all messed up.

Hi @screamerbg

All tests with ci-shield are OK with NUCLEO_746ZG

    "NUCLEO_F746ZG": {
         "AOUT": "D13"
    },

Can you close the issue ?

@sg- @screamerbg @0xc0170 please close as all the CI tests are now passed on this board
