We have tested UART3 with both Polling and Interrupt and working fine. But now we wanted to receive stream of 25 bytes each line continuously with DMA enable on UART RX.But We are unable to Receive any data with UART DMA. I dont find any example for ...
Flowing pictures have no hints to "Bufferable" attribute. Also in Cache column, some region have WB attributes which is just about caching capability; but we know that ARMv7-M architecture didn't consider any cache or cache controller inside the proc...
Hello;I want implement MPU unit in stm32F4. I have read ST documents about stm32F4xx, but did not find any thing about default attributes (write and read policies) for memory regions before enabling MPU. It means that: what memory attributes dose stm...

Dear Members,I have this code :HAL_UART_Receive_IT (&huart3, Rx_data, 4);I tested from RealTerm, it worked but I need to click "send" 4 times,How can I make it only one click for the whole string ?In STM32 side :char Rx_data[10]; char buf2 [] = "123...
For example: M7 program opens the watchdog, when the program enters hardfault, only M7 program is reset without affecting the normal operation of M4.
Hello,I'm developing on an STM32F207 and I would like to know what the procedure to execute code from RAM is?I need to modify a couple of sectors of the internal Flash but the F207 does not have banked memory so I would need to execute the flash eras...
Hello,I'm working on a low cost design which use LSI Clock. I need to compensate RC osc. deviation as best as possible.I didn't find technical datas about this. Is there any documents with precise datas on deviations according Temp. for examples and ...
