You know my number. Phone is good, but mailing list exchange is retrievable.

If you go to the extreme, things may look different.

L0 has more combined interrupts, escpecially for DMA, so DMA needs some
intermediate signal rerouting like done for the combined GPIO interrupts
(e.g. 9..15)

Could you first start with a bare .conf file.

CM3_GCC = "1"
MCU_STM32L151UC = ""
LDSCRIPT = "stm32l15XxC_flash"

Despite showing an ommision in my code just checked in, the libary compile
step succeeds.

GUI selection needs work and probably some ground up redesign.

Please send the .conf files showing th problem...
