Hi!I have module for transmit dates to SPI Interface.Data is - pointer to data buffer uint8_t.In F1 & F4 all will be ok.But in F0 & F7 modules will send *((uint16_t *)pData) (see modules below)Program for F1 or F4 will not work on F0 & F7.Where error...

thank you.---Sincerely,Vitaly.

the problem is that, when you run this line in 8 bit mode, the processor knows that it is working in 8 bit mode.hspi-> Instance-> DR = * ((uint16_t *) pData);and the processor will not execute this command, dropping into hard error.not clear another....

Hi Bob!thank you for answer.I think it's not about alignment.even if the data array is not in an even position, nothing terrible should happen.Maxim what will happen in this case, the program will not work correctly, but should not fall into hard err...

Hi!who can answer for question.Is this code fair in 8bit mode?hspi->Instance->DR = *((uint16_t *)pData);In this code program immediately go to hardware error!I think, driver for f0 & f7 in that place have fatal error!Or not?---Sincerely,Vitaly.
