Details:
I am attaching a patch that fixes some xmega problems on JTAGICEmkII.
Added support/resolved issues:
- handling (r, w, v) of the following memory types
* EEPROM
* flash (including sections: application, application table and boot)
* fuse bytes (0, 1, 2, 4, 5)
* JTAG signature
* lockbits
* production signature
* user signature
Supported xmega MCUs:
- 128a1d, 128a1, 192a1, 256a1
- 64a3, 128a3, 192a3, 256a3, 256a3b
- 16a4, 32a4, 64a4, 128a4
It was tested with an x128a1 only. Support for the rest
is based on the documentation only and is not tested.
Fixed bugs:
Segmentation fault caused by buffer overflow in jtagmkII_paged_load()
in jtagmkII.c.
Known issues:
- writing of user signature failure at verification (contents differ from
data written)
- writing of EEPROM failure at verification (contents differ from data
written) -
the same behavior is experienced with the recent [4.16.628] version of
AVR Studio - no working reference implementation is known
Still to do (among others)
- PDI physical interface support - recent version works with JTAG only
- erase operations (chip, flash, application, boot, EEPROM, user signature)
