Error: Operation exceed memory limits with STM32CubeProgrammer v2.17.0

[minnesota_pankaj]

A write of size 294KB to STM32H7A3VGHx Internal Flash works, but a write of size 775KB does NOT

BTW, same issue with STM32CubeProgrammer v2.16.0

Why does in say 0x080F0000 as the Address? That's like 64KB short of the 1MB ceiling, which is WHY it's failing.

Is this a .HEX or .ELF type file internally?

[minnesota_pankaj]

Internally it is a compressed binary file

The file size 294KB works, while 775KB does NOT

Further research shows that the STM32H7A3VGHx seems to have only 1MB of Internal Flash

So, starting from 0x0807-0000 there probably is only 512KB available after 0x080F-0000

If true, that will explain why 294KB works, and 775KB does NOT

Let me look at this more...

Right. On VG you have not continuous memory...so flash complies about it.

BUT you could make project with H7A3VI type, 2MB flash, continuous.

(And probably you have same die - same chip, just not tested and "payed for" memory. )

So try with "VI" setting, then it should work.

If you need room for big program, net time buy VI version. 🙂
