I am not sure it is only related to the power supply.
I am experiencing some really strange problems since I upgraded my desktop computer (from an old Athlon 2.6Ghz with 512MiB of RAM to a newer Athlon 64 x2 5600+ with 2GiB of RAM).
After the upgrade I simply cannot program/debug QD/QG/QE devices (both on our application boards and demoboards) using the USB Multilink Rev. C v5.72. Everytime I try to program a device I get an "Error 14" message telling me that there was an error during the loading of the programming algorithm (and always at the same address: 0x00006D).
The most strange is that sometimes I can succesfully program/debug (no error). In fact, I could succesfully program/debug these devices for a couple of weeks after the upgrade, but then, suddenly I started getting these error messages and I can't program/debug anymore.
And before someone say: yes, I tried other computers and I can program/debug on other computers. The problem is only happening on my desktop. My notebook (an Intel Core Duo) can succesfully program/debug any device/demoboard.
I tried CW6.0 and CW6.1, tried some newer programming algorithms supplied by P&E Micro, tried upgrading the USB host controller drivers, tried configuring the USB controller to work in USB 1.1 mode only, all without success.
Right now I am waiting for a solution from P&E Micro (and considering to throw the desktop through the window!).
Best regards,
