Re: GPIOv2 palEnablePadEvent configures a wrong port

After some digging, apparently this is not so simple... There are various variations in EXTI: 1) It can have the CR register or it can be in SYSCFG (width is 4 or 8 in the two cases). 2) It can have separate raising and falling edge registers on not. If we look at all STM32 sub-families the two thin...

Re: hal_Serial_nor.c

Hi, Could you verify that all IRQs use the RT macros for prologue an epilogue? do you have custom ISRs in that system? RT relies on the "latest" (lowest priority) ISR to perform the context switch, if an ISR without macros is preempted by one with macros then the context switch does not ha...

If an interrupt associated with a device happens when a transaction is not in progress then reset the device and do not process the interrupt. for (2), add an unconditional disable of DMA channels at the end of a transaction. About poi...
