I’m back with a bit of spare time so I’ve ported preview2 to Disco F769 and Nucleo F767. They work fine (except DSI display on Disco F769 for the moment).
Looking at UC5550 device.h I see you are using flash in 128bit wide dual bank from sector 0x14 to 0x17 (total 512KB). Why you don’t set (nDBANK bit in option byte) 256bit from sect 0x06 to 0x0B, it will give you ~1500KB for deployment on big STM32F76x chip…
Total deployment size is 131.968 bytes.
Incrementally deploying assemblies to the device:
- Erasing sector 3 (262.144 bytes).
- Writing sector 3 (7.560 bytes).
Assemblies deployed. There are 1.440.896 bytes left in the deployment area.
For what I see in the .map file from gcc compiler-linker the tinyclr rom code ends at 0x0804063c (ok, your bootloader need some more space …)
