Our customer has a problem:
"We tried to connect m66-ds modem to STM32F207VE, scheme in attachments. I2S initalization code is generated in CubeMX. We tried to work with I2S interface using interrupts, it worked but eventually synchronization left (synchro impulse and start of data packet are diverged in time).
There are solutions of the problem in errata, but they didn't help us."
