Is it possible to correct the STM32F429i-Disc1 manual (DocID025175 Rev3 / UM1670) for section 6.3.5 from CN3 to CN2?
I see that this section was probably a cut and paste from another devbrd kit that did not incorporate the CN3 ACP/RF E2P connector.

Resolved! Beginner problem with NUCLEO-L4R5ZI and blinking LED
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...
Why does my memset-call in an interrupt routine appears to occasionally write to the wrong address in TCMRAM?
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 ...

Internal flash memory locking (FLASH_CR->LOCK) and write protection (nWRP) - Why does the latter exist?
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...
