Using DS-5 / CMSIS-DAP to download more than about 128KB of code into SRAM of the Vybrid tower board (TWR-VF65GS10) fails with the following error message:

 

ERROR(CMD16-TAD11-NAL22):

! Failed to load "my_project.axf"

! Failed to write 155,352 bytes to address S:0x3F000000

! General error on memory or register access.


If I switch to a higher level of optimisation, and reduce code size to ~121KB, the code loads and debugs normally.

Is this a known limitation?  I was hoping to be able to debug up to the compiler limit (256KB).
