Hi,I'm realy new to this and I'm using NUCLEO-L4R5ZI with Ac6 System Workbench for STM32. I've found the board and initialized all peripherals with their default settings inside STM32CubeMX. Then I've generated the code for System Workbench and impor...
I am working with the STM32F760I-EVAL board and caching (SCB_EnableICache() and SCB_EnableDCache() are called) and MPU (MPU_Config() is called) are enabled. There are 2 things that use DMA, an SPI-bus and a UART debug logging TRACE. A portion of the ...

I am working with the STM32F446 Nucleo-144 development board. I understand that there are 2 ways to prevent the flash from being unintentionally erased/overwritten:1. LOCK-bit in register FLASH_CR2. nWRP-bits in the option bytesWhy has the second met...
Posted on June 14, 2018 at 09:48I am using stm32F411RE discovery kit. i generate a code with the cubeMX4.25, the 4GB SDHC card is working fine but when i tried with the 256MB SD Card it was not working. I am getting error 'FR_NOT_READY' in f_mount f...

Hello all,I want to use the Nucleo Board asmentioned above for sampling data with the ADCs and sending them with the USB interface to my PC. The problem is that the PC (Win 7) does not connect to this port. It doesnt appear in the device manager. Of ...
Hi,I am working on STM32L4+ (STM32L4S5xx) MCU, OpenOCD does not support L4+, https://sourceforge.net/p/openocd/code/ci/master/tree/src/flash/nor/stm32l4x.c has no support for device_id 0x470 - reported by STM32L4S5xx.There is a commit in OpenOCD und...
Looking at the eMMC requirement, it looks like HS-200 mode is limited to 1.8V/1.2V I/O levels. (From STM32H7 MCU Reference manual) HS200 Bus Speed ModeThe HS200 mode offers:• CLK frequency up to 200MHz Data rate – up to 200MB/s• 4 or 8-bits bus width...
Posted on March 20, 2018 at 16:09Hi,i have an ADC where i want to read multiple channels sequentially and than use this data. I read them every second or so, so i want to start the reading manually each time. But when its started it should read all ...
