Yes, I measure 3.3v. The 2148 runs the factory set program which plays a sound byte using the speaker which is still loaded in flash, anytime I power up with the wiggler disconnected…I found that with the wiggler plugged in, all LEDs are on continuously. We appear to be in all high impedence all the time…the wiggler is holding the device in reset…
If I disconnect the JTAG (where I have to listen the loud and annoying sound byte which is an advestisement from keil), I still cannot change the device type, only scroll through and view the different types in the list. Pretty much every button (Upload to flash, Manual Reset, ERase, Read Device ID) will, after a few seconds, give the error message “Cannot communicate with test board!” …I finally figured out that my serial cable contains all handshake signals, and that DTR was asserting RST. Removed J10 jumper, but still cannot communicate…Tried 115200, 19200, 9600, 4800…I can see a signal arriving at RXD0, capturing it on scope…Yes, I made sure that the DTR/RTS box is UNchecked…I have been using the “ReadDeviceType” all along here to no avail…been pressing reset button on board, then enter on keyboard…Any ideas anyone???
