Re: STM32MP1 support?

Ping on this thread.

What would be the cost to pay for a port for the STM32MP157F?

Re: STM32F4 "lockup" due to continuous I2C interrupts

@Edoardo1982

EXCELLENT FIX!!!!

We are using an stm32f446re device and have been having intermittent i2c failures that required power-cycle. A recent feature-addition more than doubled the i2c traffic, and the failures began to occur about 1-in-10.

I applied the recommended fix above and have ...

If not, has anyone worked at creating one?

Re: [NOTES] Multi Core support

STM32MP1 --
Is there an existing STM32 I can load for support of the M4 on the STM32MP1?

Also @giovanni - I sent you a PM with more details on what drives my question. Thanks!
