Howzit

Need some advice tried to read D Flash data with XProg Box 5.5.5 clone no dongle software - having this error Unknown MC9S12 device .Part ID:0x2004C482
Tried to read a few times same error just the Part ID that change to 0x0024C48A
At some stage I got error Partition corrupted Partition dump: 00 00 00 10 Select partition size manually

Advice appreciated

If all the connections are good in the FRM pcb , can be Dflash problem
Can you read P-Flash or eee ?

[rtbdiagnostic]

I tried to read d - flash with upa usb reads quick but dump differs everytime - I did read P-flash with i-prog
Never tried to read p-flash or eee with x-prog
Would you think better to downgrade to perhaps 5.5.1 would it be more stable perhaps

Check connections again
Graab other dumps width same numbers and coded it

firmware version 5.5.5 is very unstable even with eeprom spi reading
so anything is possible

Found this procedure to downgrade would it be the correct way to follow to get back to 5.5.1 firmware

Would you recommend X-prog 5.84 to read write FRM

[rtbdiagnostic]

Or would it be advisable to install on Windows XP 32 bit OS instead of Windows 7 64 bit

Is it necessary to short X-tal on the FRM PCB
