Posted on July 16, 2014 at 07:46Hi All,Using the standard Cube (F4 v1.30) HAL_SD drivers, I randomly get the SD_TX_UNDERRUN'' error when writing using HAL_SD_WriteBlocks().It happens totally at random.I have tried:- using older libraries - same resu...
Posted on March 03, 2015 at 20:35Hi ST Forum,I want to implement a DMA RS232 device (with a MAX232 transceiver), where if the master sends a certain message (e.g. 0x01), then the STM32 will send back a certain message (e.g. 0x02). I got the DMA Tran...
Posted on March 24, 2015 at 16:34When I look in my startup_stm32f427_437xx.s file. It says: .syntax unified .cpu cortex-m3 .fpu softvfp .thumbShould it say .cpu cortex-m4?
Posted on March 20, 2015 at 13:58I know DMA acts as a channel where the CPU gets bypassed while data is transferred between Memory/ Peripheral,and in the mean-time CPU can execute useful operations..But my question is ...If the DMA transfer is going...
