I am not able to get any of the eeprom_write_* or eeprom_update_*
functions working on an XMega32E5. There are no compile errors or
warnings, the functions just don't do anything. The eeprom read
functions that I am using all work fine.
I had previously been using a version of avr-libc that I lifted from
AVRStudio 6.2 to get support for the E5. The eeprom functions worked
well on that version.
I compiled it using gcc-4.9.3 on Ubuntu Trusty.
Atmel's nvm functions work for me, but add a significant amount of code.
I would rather use the ones from avr-libc, since I use them for all of
my other AVR projects.
Looking through the code and the docs it seems like the functions should
work.
I have done a number of experiments, including writing a fixed value to
a fixed location on boot then reading the eeprom out with avr-dude.
Nothing I have done has produced a successful write.
What more information do you need, or what tests can I run to help debug
this?
Thanks!
Scott =)
