Keil 2140 eval board
2005-12-17 by dodge1955
Has anyone had any problems getting the Philips Flash Serial Utility (either 2.2.2 or 2.2.3) to work? I have gotten into the situation where I have downloaded code that has the JTAG turned off (not intentionally, of course) and it gets locked up. The only way to reprogram it in that state (supposedly) is thru the serial port. But, I have always gotten 'Cannot communicate with test board" and it locks up my serial port until I reboot my computer. This on two different machines. I have been working with Keil tech support, but they still do not have an answer. I ended up sending back my board, getting it reprogrammed (so, it wasn't dead), but now it is back in that condition again. And, I can't get the serial port working again. They are again helping me, but still no answers yet. Very frustrating when I'm still just learning how the chip works. Sutton
