# Burn a HEX file into Brenner8 using linux

I have got a version of Brenner8 called AEI when I try to burn my HEX file into PIC16f877a using command

 usburn -w -s40 -F16 -Ifilename.X.production.hex


I got this output

usburn V 0.4 (16.05.2010) by sprut (www.sprut.de)

• I'm going to guess that you have the chip actually inserted when you run it... – Ignacio Vazquez-Abrams Jun 6 '15 at 15:52
• No I connect it to the laptop then insert the chip – Nasser Jun 6 '15 at 15:57

I got this output...

no calibration data

The programmer must be calibrated before use, to set the Vpp voltage range. An uncalibrated programmer can produce up to 30V! The chip you tried to program is probably fried, so throw it away and try another one after calibrating the programmer.

Brenner8 Calibration under Linux

• When I try to calibrate it by using usburn -k it gives the same output when I try to run any command from usburn it gives me the same output – Nasser Jun 16 '15 at 5:24
• Same as what? Were you able to complete the calibration procedure? Does it still say "no calibration data"? – Bruce Abbott Jun 16 '15 at 9:33
• I have measured the Z-voltage from the Zener diode and it gives me 3.28 then I connect Brenner8 to Laptop and type in the terminal usburn -k as in the calibration manual but when I press enter it gives me no calibration data – Nasser Jun 16 '15 at 11:50
• What did it say when you started the calibration? Did you get to calibration step 3, and what did it say then? – Bruce Abbott Jun 16 '15 at 21:02
• In the first step when I type usburn -k it gives me no calibration data – Nasser Jun 20 '15 at 7:26
