In the linker scripts for G491 and G4A1 the RAM size seems to be 128kB but on G4 series web page statement is 112kB. One of the two is false.

Hi @atsju,

Thank you for your contribution. The reported issue has been confirmed and a bug tracker has been opened internally. The following fix in the flash files .icf will be implemented and made available in future release for all STM32G4 series, where the RAM size will be the sum of SRAM1 and SRAM2.
