Can anyone direct me towards a JTAG still manufactured and sold for use with the M8051EW. It seems as though most manufacturers have ceased production for a number of reasons. Since this 8051 variant supports JTAG I was hoping to be able to use this feature. The most promising is/was the MIPS FS2/System Navigator but cannot find a seller. I have a ULINK2, but the [Project][Options][Debug] drop-down does not allow/support selection. The MON51 and ISD51 use system resources, so I would prefer to not use them. Thanks.
Apparently not a big seller.. a problem using odd/proprietary hardware/ip
You'll either need to dig equipment out of the secondary market, find some consulting group with specific experience, equipment and expertise, or use other methods.
If you can write functional code, ie not require single step to understand what you've written, you can use a serial port to understand flow and function, and provide a debug monitor type interface.
All,
.........sigh................
Thanks. Will keep looking. Anybody comes across one please let me know.
