i want use some .bss section via ghs pragmas for a bootloader jump var in retention ram.
but the vars inside my shared struct are only written sometimes.
A voltage reset helps it works in 30/100 cases.
But often my vars are not writable and seem to be locked.
The RAM on RH850 is ECC protected, and the ECC applies to 32-bit words. Consequently, you must initialize the RAM by writing every 32-bit RAM location before a 16-bit or 8-bit write would work correctly…
