My programmer is a MQP Pin-Master 48 <http://www.mqp.com/pm48.htm> which directly support the PSD chip via JTAG (JAM STAPL files). According to this document: <http://www.mqp.com/pdf/apnotes/30201.pdf> the programmer does not support "auxiliary" functions like "reading" the device, but only erase/program/verify. The official programmer/software (FlashLINK/PSDsoft Express) < http://www.st.com/internet/com/SOFTWARE_RESOURCES/TOOL/CONFIGURATION_UTILITY/um0050.zip> permits to "dump" the content of the PSD in an .obj file, but at this date I have not this programmer and I have to build it < http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00004566.pdf> :-( If you are able to dump the software using your Galep 5, you are welcome!!! :-) Otherwise my two options will be: 1) to build a FlashLINK clone, hoping the PSD contents are not protected: according to this document < http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00004566.pdf> (Pag. 17) the protection flag can't be enabled using the JTAG interface... 2) to remove the PSD chip and read its contents using a different microprocessor (this will work for certain) _ Elio. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
