Re: Difficulty understanding mutexes and context switching

Hi,

S-functions reschedule internally, context switch always happens in critical sections in ChibiOS.

chCondSignalS needs to re-enable interrupts


This is your wrong assumption, it does not need that. Try single stepping inside an S function in asm.

Re: add checks for DMA cache synchronisation function

Invalidating non aligned objects (address AND size) is a very bad idea, this would mean corrupting adjacent data. Flushing is not a problem.

STM32G0xx support

Hi,

This topic is dedicated to STM32G0xx support in HAL.

I just started committing code for this so this thing is "officially" started. I am starting from the L4+ files, the clock tree appears to be a subset of the L4+ one.

Re: STM32F4Discovery USB Mass Storage via OTG

Please look at demos, you are missing entirely the "connect" part: mmcConnect().

Also, enable assertions in chconf.h, those can catch this kind of errors.

I think the RM is wrong too, I fixed like in cubemx.

Re: Internal Flash Driver

Just implement it as you see it right, we will discuss details later.

My only point with DBM is that two driver instances would interfere each other because would work on the same internal peripheral. I did DBM for L4 but then removed it because this.
