gd32vf103inator's Issues

Built binaries

Hello,
could you please post binaries of the DFU loader and longan nano example ? I am having trouble building the code correctly - it freezes in some (usbfs, dp_init, also printf) functions. It would be nice to have reference code to compare to :-) So far i know that: interrupts, gpio, rcu, and mtimer are working correctly.

thanks

structures gd32vf103_* are not packed.

Your structures that "map" to register space are not packed. It is probably ok for uint32_t filled structures, but other sizes might get padded.

Building with Clang

Have you tried building with Clang? To make it compatible for both compilers, not just GCC.

There are many incompatibilities with assembler directives and linker script style.

It might be worth mentioning that the Longan Nano has differing amounts of flash and ram

I struggled for a few hours uploading your bootloader, only to realize that my boards had GD32VF103C8 instead of GD32VF103CB chips, basically 64K flash, 20K ram. I figured they would all be the same, but evidently I got a cheap assembler. Just wanted to throw that out to save someone else some trouble.

I've got it working out great now though, thanks!
