Resolved! Hello, I'm using an STM32H750 MCU where I'm integrating the Crypto lib v4.0.1 I would like to execute this library (.text) from a specifc section. But I can manage to do what I want.
You can found below a extract of my linker script:MEMORY { D1_CODE_RAM (xrx) : ORIGIN = 0x24070000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 128K NVRAM (rx) : ORIGIN = 0x8020000, LENGTH = 64K } .ram_code_load...
STM32G031K6 - self-locking procedure and cannot reach MCU anymore through SWD
Hello, Having an issue with STM32G031K6Ux MCU. Below added function that checks Options bytes, and if needed - makes changes (power re-cycle is needed after it).This function CheckOptionBytes() works OK on several MCU's. But on this MCU we have an is...
Resolved! STM32U585 / B-U585I-IOT02A: Can't enable GPIOI via RCC_AHB2ENR1
Hello,I am trying to access the MX25LM NOR-Flash chip on the B-U585I-IOT02A board via OCTOSPI2. The nCS pin is connected to PI5. However, attempting to enabe the peripheral clock for IO port I by setting Bit 8 (GPIOIEN) of register RCC_AHB2ENR1 fails...
