just hooked the ChipKit UNO32 to my Windows 7 laptop. Tried to load Blink sketch. Keep getting "verification error first mismatch at Byte 00x0180 0x00!=0xff, verifcation error, content mismatch". Looks like there is error during the upload. The green led LD4 blinks continually. Any pointers on how to fix this? Do I have a bad ChipKit Uno32 board? thanks B

There is a known issue with an older version of the bootloader that could be causing this problem. Do you have a means of flashing the latest bootloader (such as a PICKIT or an ICD)? If so you can download the latest bootloader from the Digilent Uno32 web page.
