I have configured the ADC to use pins 1,2,3,4 for DMA transfer. I do get COM port output, however, I noticed that the outputted numbers aren't as they are supposed to be. The values for only 2 of the 4 pins change as they should. The other 2 do not.T...
Hi, I'm working on root cause a Hard Fault issue on STM32H563. The application is a regular ping and response. The system has TrustZone enabled. When the hard fault happens, according to pushed stack info from psp_ns, the call happens inside a mem...
Hi I am trying to commuicate between two boards through UART.One board is nucleof4 and other board is a processor.Im sending a data from nucleo to other board(where data gets displayed) through HAL_UART_Transmit(&huart1,(uint8_t*)"Connect",sizeof("Co...
I have 2 boards, basically identical except one has PHY KSZ8091RNA and the other has KSZ8091RND.Both use the STM32F429NIH6.The only difference I can find in the two PHYs is that I need to set to set the REFCLOCK bit in KSZ8091RNA's PHYC2 register. W...
Hey. I would like some clarification regarding writing to Flash memory. Specificially, 4 bytes (float values).I have the following code: void FLASH_write_single_float(uint32_t address, float data_to_send) { if (address < 0x080E0000 || address > ...
Hi Folks, I'm working on pattern generation on GPIO pins and I've done it successfully using bare-metal programming approach. I used TIM1 to trigger DMA2 to take data from a buffer and send it GPIOA->BSRR. But when I try to change the timer from TIM...
Hello, on an STM32F407 I am experiencing a Flash Erase/Write error. The odd things is that it happen only the first time after boot, the following times after the error I can write with no errors. But, if I erase and write in the Init phase, bef...
Hello everyone,I'm configuring a STM32L0 core board to connect to a module using AT commandAll the commands work fine but when I get to a given command (AT+MSG="123456"\r\n), they work only the first time and the second time it only sends ATfor examp...
We are using STM32F105VCT micro in our product from many years.In the recent hardwares, we have seen that input logic level is changing only with 200mv change.When the input voltage to any port pin is crossing 1.5 we are seeing as logic level 1, when...
