Hi Martin,

I came across this and though you might want to have a look at gd32vf103inator. The interrupt controller on the gd32vf103 has a vectored mode and some special CSRs to handle nested interrupts and tail-chaining.

In the same repo is also code to get USB up and running and a DFU bootloader that works with a non-patched dfu-utils.

Hi Emil, Thanks for the information. However, I think the current configuration is good enough for demonstration purposes. If you need vectored and nested interrupts etc. you are free to do the reconfiguration for your specific application need. /Martin
