Here it is the script I made to build my Linux/GCC cross-compiler

Here it is the Makefile that works

My procedure to upload a .bin executable to the CM-5 :
* lauching
gtkterm (As minicom but with a more handy user interface)
* setting the connection to 57600 bauds, 1 stop bit, no parity bits, no stream control
* doing the
#-and-red-button trick to enter in the bootloader (Matrix, here we come
)
* typing
load in the
gtkterm shell
* sending my .bin file with the
gtkterm ASCII file send functionality
* it's done, don't care about the CM-5 checksum complaints
