Resolved! STM32L433: can't make sense of Flash Loader Demonstrator
During development I've been using ST-LInk to program the STM32L433 which of course works perfectly. I want to release the firmware and allow users to be able to update the code over UART2. I've set BOOT0 and can see the device using the latest versi...
Board to board bi-directional SPI+DMA data corruption issues
Posted on July 17, 2014 at 18:45I have two discovery cards setup for bi-directional SPI. On the slave, I'm using SPI3 with DMA1 support (TX stream = CH0_S5, RX=CH0_S0). I have the TX stream flow control configured as DMA_FlowCtrl_Peripheral (tried b...
