Posted on June 22, 2015 at 10:14I have a custom STM32F411-based board that I am trying to bring-up. But when I plug this into the USB port, I do not see the device listed.Is there any documentation/guide that can help with initial board bring-up?I a...
Posted on June 22, 2015 at 11:33Hello,HAL_RTC_SetTime fails when trying to set new values on the RTC due to RTC_EnterInitMode timeout.while((hrtc->Instance->ISR & RTC_ISR_INITF) == (uint32_t)RESET){ if((HAL_GetTick() - tickstart) > RTC_TIMEOUT_VALU...
Posted on June 20, 2015 at 09:10Good day,I have a bit of a problem, is it possible to use SDIO with smaller buffers and have decent speed.I tried to do few tests with smaller buffer like data_buffer[512], data_buffer[1024]...And have really poor spe...
Posted on June 21, 2015 at 09:13 Hi, I experiment an issue while writing data on flash. For testing purpose, I made an app that writes several sequence of 'a' to 'z' char to flash. Each uint_32 data contains 4 chars (a-d, e-h, ...). I use : HAL_FLAS...
Posted on May 11, 2015 at 13:14Hello, I have some problem with USART2 (stm32f373). USART1 is working with same code but, Usart2 does not work. here is the code. void Uart_Int(void) { GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_...

Posted on June 21, 2015 at 14:51Hello again!We have designed the board with this processor, it works perfectly.But in 1 : 100 times it seems as there is some weird condition and the processor wont initialize at all.If this situation happen, then I c...
Posted on June 20, 2015 at 20:02Hi,I am debugging the SPI interface on the STM32F427 for a while now. I am using SPI1 and SPI2. SPI1 works just fine, I am able to transmit and receive data just fine. Now I am struggling to get SPI2 to work fully.I c...
