I try different board, and with original state the board boots fine with the default jumper settings, and everybody is happy. But no PCI Agent, the board will stop after 1 minute in a PC.

 

                Step 1 for PCI Agent: Set the MSB bit to 0

 

 cp.b  FE000000 100000 20000  ; copy 128K block to RAM

 md.b  100020 8               ; display original contents

 mw.b  100020 34 8            ; 34 was the original value is B4 with MSB = 0

 md.b  100000 40              ; reconfirm HRCW

 protect off all              ;

 erase FE000000 FE01FFFF      ;

 cp.b  100000 FE000000 20000  ;

 protect on all               ;

 cmp.b 100000 FE000000 20000  ;

 

                                Now, the board doesn’t boot outside the PC, or in the PC…

Now we try with 04 like  the PCI agent mode from BSP (we look at memory dump exemple)

                        cp.b  FE000000 100000 20000  ; copy 128K block to RAM

 md.b  100020 8               ; display original contents

 mw.b  100020 04 8            ; 04 is the value in the HCRW_AGENT file

 md.b  100000 40              ; reconfirm HRCW

 protect off all              ;

 erase FE000000 FE01FFFF      ;

 cp.b  100000 FE000000 20000  ;

 protect on all               ;

 cmp.b 100000 FE000000 20000  ;

 

                                Still, the card doesn’t boot in the PC or on the bench…

 

thx Martin
