I'm trying to get to grips with SiLabs IDE in order to transfer my many asm source files from a very old METAI based development system to the SiLabs IDE (was warned off the Symplicity suite due to its 'c' bias).
I'm reduced to merely trying to get the Blinky.asm example to work with a second source 'init.asm' that simply sets up a serial port.
(Already got the, as provided, blinky to work fine.)
So blinky.asm has a ljmp Main at ORG 0, and I want Main (in a segment called Blink) to be at 100h.

rseg Blink ; Switch to this code segment.

Main: lcall Init_Device
anl PCA0MD, #NOT(040h) ; clear Watchdog Enable bit
etc
******************************************
Init_device is in a separate source - Init.asm - with a segment name 'init'.

Both sources assemble without error.
I'm linking with an additional directive on the BL51 linker to try to force code to 100h.
Here's the build result, with the error.

I clearly have a segment 'blink', so do you know what the linker is objecting to?
