Hi! Noticed a typo in the system configuration controller (SYSCFG) register map in both reference manuals RM0399 (Rev 4) and RM0433 (Rev 8). The SYSCFG_CCCR register is at two different offsets (0x28 and 0x2C) and SYSCFG_PWRCR is missing. I think, S...

Why are you enabling the fractional mode, when you program the integer mode (RCC_PLL1DIVR) from the PLL?rcc.pll1fracr().write(|w| w.pll1fracn().bits(0)); rcc.pll1cfgr().write(|w| w.pll1fracen().set_bit());The initialization flow according the TRM...

Could be an permission issue.The required udev rules are in /etc/udev/rules.d directory?Normally they must be installed manually. They can be found under the install path form STM32CubeProgrammer Drivers/rules.

As alternative to external tools, is to write a top level linker script and let GCC (linker) do this job. This linker script is from one of my projects, but for a AVR MCU. But with some modifications, it should also work on STM32 devices:top.ld:OUTPU...

Are there any reason why don't use the official precompiled GNU toolchains binaries from ARM?ARM GNU Toolchains for R/M-Profile (binutils, gcc, newlib) ONLY*:https://developer.arm.com/downloads/-/gnu-rm*) Toolchains only, no STM32 libraries like HAL
