| Hi Matt, had worked with the Debug Monitor on an UP2000+ some time ago. It is normal for the SROM console to print some alphanumerical values. Unfortunately my UP 2000* is disassembled at the moment therfore I cannot compare your values. To load the Debug Monitor you need the dp264dbm.cmp file. Had same problem with the transfer rate - it works only at 9600 baud. On a working system the Debug Monitor starts with a short instruction. If you have a graphic card installed it comes up even with the graphics console. I am not shure if this "06" has anything to do with the POST Code. To verify this you need to insert a POST Code PCB in preferable the ISA Slot. From your description I would assume you have problems with the SDRAM controller - any one of the Dchips or some soldering problems. To fix this it's quite complicated as there is no direct access to the pins. Try to use another startaddress than 300000 for xload. The size of the DBM is 0x32d34 maybe you can find a working slot of that size. I was once lucky on a LX164 board and could locate the faulty address. On the LX164 and SX164 systems the SROM Mini Debugger is not present within the "production" SROM. With a MMJ cables and a MMJ->DB9 adapter you will not be able to see anything. First you have to burn a new SROM which has the Mini Debugger implemented - is included in the "ebsdk". The Xilinix chips are only ROMs - so you need new SROMs which are very expensive. ATMEL offers EEPROMs which can be reburnt but you need for this at least special adapters as most standard PROM-Burners are not specified for SROMs. I am planing to rebuild my UP2000+ again.If you need more information I could do some more tests.
