[Bug 1400185] Re: avrdude crashes when eeprom is read

 

The original post was with USBtiny with firmware 1.04. I upgraded
USBtiny to 1.07 and I still can observe this problem.

To find USBtiny firmware version:

$ sudo lsusb -v | grep -A2 0x1781
  idVendor           0x1781 Multiple Vendors
  idProduct          0x0c9f USBtiny
  bcdDevice            1.07

And I want to add another bug with avrdude (or USBasp). I see it when I
work with AT90S2313, it is legacy chip that was replaced with
ATtiny2313. I can read flash only once, when I try to read it for second
time, I get an error. I have to replug my USBasp programmer and I can
read flash again. It is 100% repeatable pattern.

Read flash of AT90S2313, first time, we can read it:

$ sudo avrdude -c usbasp -p at90s2313 -U flash:r:xx.bin:r -F -B5

avrdude: set SCK frequency to 187500 Hz
avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100%

avrdude: Device signature = 0x1e9101
avrdude: reading flash memory:

Reading | ################################################## | 100%
8.19s

avrdude: writing output file "xx.bin"

avrdude done.  Thank you.

Try again, and we have an error, target doesn't answer:

$ sudo avrdude -c usbasp -p at90s2313 -U flash:r:xx.bin:r -F -B5

avrdude: set SCK frequency to 187500 Hz
avrdude: error: programm enable: target doesn't answer. 1 
avrdude: initialization failed, rc=-1
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x588460
avrdude: Expected signature for AT90S2313 is 1E 91 01

avrdude done.  Thank you.

Title:
  avrdude crashes when eeprom is read

Status in avrdude package in Ubuntu:
  New

Bug description:
  Ubuntu 14.04.1 i386
  avrdudude 6.0.1-1

  I try to read EEPROM from Arduino board (ATmega328p) with USBtiny ISP
  programmer.

  FIRST
  It crashed regularly. There is a report that free() detected memory allocation problem. EEPROM is empty, all 0xff; this can be important to replicate this crash.

  # avrdude -c usbtiny -p m328p -U eeprom:r:xx.bin:r

  avrdude: AVR device initialized and ready to accept instructions

  Reading | ################################################## | 100%
  0.01s

  avrdude: Device signature = 0x1e950f
  avrdude: reading eeprom memory:

  Reading | ################################################## | 100%
  17.15s

  avrdude: writing output file "xx.bin"

  avrdude: safemode: Fuses OK (H:05, E:DA, L:FF)

  avrdude done.  Thank you.

  *** Error in `avrdude': free(): invalid next size (normal): 0x093d5360 ***
  Aborted (core dumped)

  
  SECOND
  When I write data to EEROM, it can be all 0xff, I read back different data and verification fails. It is good that it is detected but 100% of EEPROM is read to find that the first byte doesn't match. This can be improved, USBtiny is slow...

  THIRD
  Write data to EEPROM doesn't work, see previous point.
  # avrdude -c usbtiny -p m328p -U eeprom:w:xx.bin:r

  I tried USBasp programmer to the the same with Arduino and it works
  good so my troubles are related to USBtiny programmer. I cannot say if
  problem is in avrdude or in firmware of USBtiny programmer.
