STM32G474 failed to erase chip.
I use J-Link and STM32G474, which can burn the program, but can't erase the chip. After trying to use J-Link STM to unlock the chip, it also did not work Application log started - J-Flash V7.92b (J-Flash compiled Aug 23 2023 14:00:43) - JLinkARM.dl...
PWM Complimentory signal is not getting with HAL_TIM_PWM_Start_DMA
Hello experts I am trying to make a PWM signal from DMA , with PWM + complimentory channelWhen i use HAL APIHAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sin_table, 32);// Here I get the signal as expected But when I Use HAL APIHAL_TIMEx_P...
HAL + FreeRTOS + FatFS Bug
Hi,We have come across a bug in the code generated if you use FreeRTOS in STATIC memory mode (rather than the default dynamic mode) , with FatFs. (All generated from the CubeMX).When we run the code we get two CONFIG ASSERTS in the RTOS and it is due...
Problem reading NAND Flash ID with STM32H725
Hello all,we have built a board with an STM32H725. The FMC-Interface is used for a PSRAM connection to an FPGA and a connection to a NAND flash with 8 Bit databus.The initialization routines are created by STM32CubeMX. The PSRAM interface to the FPGA...
Can I use a nucleo64 st-link to program and power an external MCU?
Hello,I have a NUCLEO-F446RE board, lots of homemade boards with little MCUs (STM32G030F6, STM32F103C6, ...), some blue pills and programmers. Only the first ones I bought has an original chip. The other blue pills and programmers, the vendor lies an...
Resolved! STM32U595 used PA11 and PA12 as gpio
I used PA11 and PA12 as standard GPIO in STM32U595ZJT6Q and system frequency is 4MHz. Config PA11 and PA12 to PP output mode ,no pull up.Don't set this gpios to high, the mini system current is 3mA,but set this gpios to high, the current is 22mA.Test...
Resolved! Screen is terminating
Hi, I'm using an STM32F401RE board for a class(programming using MacOS). Right now, I'm using VSCode and make to edit and compile my code, then using stlink to flash it. All I'm trying to do is print hello world to the tty.usbmodem* screen in the /de...
hrtim hal library
hi, I was looking for HAL -library for stm32334r8 MCU but i dont see anything about HRTIM in the avilable HALY library. where can I find HAL instructions documentation for HRTIM ?
Resolved! Issue writing 32-bit AHB transaction to 8-bit FSMC peripheral, STM32U575
Hi,I'm trying to write RGB data directly to an 8+8+8 bit i8080 screen using the DMA2D and FSMC peripherals on a STM32U575 Nucleo board. As a test, I set up the FSMC and manually sent data one uint8_t byte at a time - this works fine. However, I'd lik...
