Resolved! Recast a const int16_t[] array to a int16_t[] array, why can't I re-write the element in the recasted array?

Hi, community,I am converting a TI CCS project into STM32 project.In the TI CCS project, a const array is defined in the file array.c, e.g.const uint16_t ARRAY[] = {0, 1, 2, 3, 4, 5};and in the main.c, the array is recast asextern uint16_t ARRAY[];an...

Local variable overwrite global variable

Hi,I'm facing a problem in the managing of local variables on STM32WB50CG with the STM32CubeIDE version 1.14.1.Specifically, the code must perform a write via the sprintf function on a local variable (allocated at address 0x20009bd8).ALL the writings...

STM32CubeIDE no longer generates PLLQ higher than 33MHz for G03X since version 1.15.0

Version 1.15.0 and also 1.15.1 wrongly limit PLLQ to not greater than 33MHz regardless what VCO is.The reference manual says 128MHz or 32MHz are allowed for high and low VCO. But only 32MHz is allowed for 1.15.0 and later. Older versions do not have ...
