Re[2]: [Sdcc-user] Preventing SDCC from initializing stack pointer

[Felix B. <fb...@lt...>]

Hello Lon,

Unfortunately this would not work, since it is not just a boot loader
that gets out of the way when the user application runs. Quite much of
the work is done by the firmware which has access to the user
application by means of callbacks. Hence there is a permanent
communication between firmware and user application which live in
parallel.

Any other ideas ?

Many thanks for your help, Felix
