STM32F7XX bootloader unable to erase.
Hello,We already have developed a USART boot-uploader for a project of ours, testing it on an STM32F7XX customized board. I can bring up the bootloader by init command ( 0x7F ) and get a response 0x79 ( ACK ). But an extended erase command fails to r...
When do we need to call Clean and Invalidate D Cache?
Hi everybody, this maybe a very simple question but it is complex to me.Are they only needed between DMA and Memory?If we have few buffers but they are same RAM, do we need to clean/invalidate before copy or read?If a buffer is located in uncache (by...
