Petre,

According to the Manual:

www.xess.com/manuals/xs40-manual-v1_3.pdf

You have series of programming shunts. Of interest is J7.

"The shunt should be installed on pins 1 and 2 (ext) if the 8031 microcontroller program is stored in the external 32 KByte SRAM (U8) of the XS40 Board."

XSLOAD is described as a program to load your micro. The Manual also addresses you micro problem (using Erik's solution)


"executing microcontroller code from internal ROM instead of the external SRAM on
the XS40 Board. (You will have to replace the ROMless microcontroller on the XS40
Board with a ROM version to use this feature.)"

There looks to be a FAQ @:

www.xess.com

I have been interested in this board let us know how it works out.

regards,
p
