Is it possible to change the FLASH write protection at run time without reprogramming the option bytes?The write protection registers are writeable after unlocking, but it appears as if changing the value has no effect on the actual write protection;...

I'm working on a project that's using an STM32G484CEUX. The WRP2A and WRP2B registers are not showing under the FLASH peripheral of the SFRs tab:The device is running is dual bank mode.I have added them to the .svd file, but I think they should alrea...

I've got the following interrupt configured for TIM4:void TIM4_IRQHandler(void) { if ( LL_TIM_IsActiveFlag_UPDATE( TIM4 ) ) { LL_TIM_GetDirection( TIM4 ) == 0 ? ++x : --x; LL_TIM_ClearFlag_UPDATE( TIM4 ); } }I know this interrupt is bei...

I have a Touch-GFX project that I can program into an STM32H7B3I-DK from within the STM32CubeIDE.However, trying to program the same board with the project's .elf file from STM32CubeProgrammer fails with:16:20:21 : Memory Programming ... 16:20:21 :...

Thanks, I get that.However, the documentation does not make it clear that modifying the WRP registers allows the option bytes to be updated, but it does not immediately change the protection that is enforced.

Possibly very slightly if there is a command sequence needed to remove it temporarily.The block is used to store parameters that only change infrequently but which are critical to normal operation. Other memory devices support "protect all", but allo...

I would start by looking at what IEC60601 says.

The MX25LM51245G_STM32H7B3I-DISCO External Loader is needed to program the system.It was appearing to work as the erase did not erase the external NOR FLASH, so only the MCU needed to be programmed to get it running (though probably not if the code h...

Strangely, it appears as if the programming may actually have worked, even though it is reported as having failed!The application appears to work correctly if I disconnect the programmer or set it to "Run after programming". I have verified it is pro...
