EEP/I2C WR 2 bytes ci-test FAIL on some STM32 platforms

[bcostm]

Description

• Type: Bug
• Related issue: NUCLEO_L476RG Issues #2957
• Priority: Major

---

Bug

Target
NUCLEO_L476RG

For info, the test is OK on NUCLEO_F429ZI, NUCLEO_F412ZG, NUCLEO_F401RE
Seems related to the I2C IP version embedded in the MCU. To be checked.

Toolchain:
GCC_ARM

Toolchain version:
5.4 2016q3

mbed-os:
mbed-os-5.4

Expected behavior
Test is PASS

Actual behavior
Test if FAIL

Steps to reproduce
'mbed test' + ci-test shield

@bcostm
Just tested ok with ARM and GCC_ARM here ... there must be something different, so needs to be understood

@bcostm - I think this is due to ARMmbed/ci-test-shield#22
The I2C library needs to be updated, which I've done locally, but this hasn't been done in the ci-test-shield official repo yet ...

[0xc0170]

This should be now resolved as ci-test-shield was fixed

[bcostm]

Just for reference, I have verified the I2C tests and they are OK now.
