eBay Systemyde 41CL v2 - can't update

[Sylvain Cote]

Try this modified sequence:

Code:

Typed             Executed          Description
XEQ "MMUDIS"      MMUDIS            disable MMU
XEQ "MMUCLR"      MMUCLR            clear MMU configuration
"YFNX"            "YFNX"            41CL Extreme ROM image (instead of YFNZ extra)
XEQ "PLUG1L"      PLUG1L            map YFNX to page 8
XEQ "TURBO50"     TURBO50           50x speed-up
XEQ "SERINI"      SERINI            initialize serial port
XEQ "BAUD48"      BAUD48            set serial port speed to 4800 baud
XEQ "MMUEN"       MMUEN             enable MMU
"830000-0FFF"     "830000-0FFF"     load incoming module 4K image to page 830 in 41CL RAM
XEQ "YIMP"        YIMP              import 4K module from serial port using YIMP from YFNX module

Still, even if the serial cable is not plugged, YIMP should show you these messages: "RECEIVING" for ~10 seconds then "TIMEOUT".

Oh, wait, I remember that there was an issue with the original YIMP that was not waiting if there was no character in the UART incoming buffer.
I also remember that I was able to get over it but the solution was lengthy and convoluted.

Using the above configuration, try this:

Code:

Executed          Description
"830000-0FFF"     load incoming module 4K image to page 830 in 41CL RAM
MMUDIS            disable MMU
YIMP              YIMP from YFNZ (extra) module -> do you get the "RECEIVING" + "TIMEOUT" messages ?
MMUEN             enable MMU
YIMP              YIMP from YFNX (extreme) module -> do you get the "RECEIVING" + "TIMEOUT" messages ?

If the above test is not working and since you are in USA, I would suggest that you contact Monte and ask him if he could directly flash the board (with JTAG) to the latest ROM images.
