NUCLEO_F446RE Issues #2959
Description
Description
- Type: Bug
- Priority: Major
Pinout issue
There is a strange issue with the pins on this board.
It's better explained as comparison between F446 and L476, e.g.
ST Nucleo L476 (correct sequence)

ST Nucleo F446 (incorrect sequence)

It seems that LEDs on D1, D2, D4, D5, D7, D8 cannot be high, though D0, D3, D6, D9 function normally. This is mostly noticeable in the first sequence when LEDs are turned on in triplets, e.g. D0+D1+D2, D3+D4+D5, D6+D7+D8, etc.
The example program can be found here

Interrupt failures (InterruptIn)
InterruptIn on D2 throws greentea error, I suspect that the test crashes
InterruptIn on D3-9 are skipped due to the error with InterruptIn on D3
(Note that unlike the other reports, no InterruptIn works)
## I2C failures with EEPROM (I2C)
I2C - EEProm Read (fails with ARMCC, GCC)
I2C - TMP102 Temperature Read (fails with GCC, works with ARMCC)
