When I used
defmt-rttwithqingke-rtand flash withwlink, it produces a ~500MB binary that failed to flash.Turns out
defmt-rttplaces its RTT buffer in.uninit.*sections and expects them to be NOLOAD. Sinceqingke-rt's linker scripts don't define a.uninitsection, the linker places these symbols in a default loadable segment with a RAM VMA (0x20000000+).wlinkinterprets the RAM VMA as a flash offset, so the output binary spans from 0x00000000 to 0x20000xxx.This PR adds a
.uninit (NOLOAD)section after.bssin bothlink-highcode.xandlink-no-highcode.x, matching whatcortex-m-rtdoes.
