  1. Hi there. I've got a problem with a PIC Burner i've made recently, hope you could help. Burner is succesfully found by P18, it passes all tests (VDD, VPP and so on) and PIC is correctly identified as "PIC-Typ PIC18F452 Rev. 7" (i'm not shure about revision, anyway). BUT. When it verifies written hexfile (mios_bootstrap_loader_v1_1b.hex) it reports the following: compare PROGRAM, ID and EEPROM : -->744 errors in PROGRAM -->8 errors in ID -->0 errors in EEPROM Start write Configuration --finished compare CONFIG : -->0 errors in CONFIG Errors number in PROGRAM varies from 730 to 744 and sometimes there are some errors in CONFIG. I've tried all different timings but it didn't affect number of errors anyhow. I also tried to burn it three times in a row without erasing it - not a big difference. I also noticed, that "contense of PIC in programmer" is different every time i try to burn it. I mean, code could be anywhere, even in different panels. Hope, you could help me with this issue. Thanks a lot.
