Follow-up Comment #33, patch #9543 (project avr-libc):

wdt.h seems to have some issues that need fixing up. The wdt_enable() and
wdt_disable() macros seem are completely inapplicable to the ATtiny416.

There seem to be similar issues in sleep.h

Follow-up Comment #32, patch #9543 (project avr-libc):

Updated avrxmega3-v11.diff.xz with latest AVR8X devices.
Rebased on latest *.ATDF (AVR8X only entries):
 Atmel.ATtiny_DFP.1.10.348.atpack
 Atmel.ATmega_DFP.1.7.374.atpack
Header generator error fixed for DWORD types (size=4).
Add FUSELOCK_DEFAULT values (as per newer original *.h)
New devices:
 attiny424, attiny426, attiny427,
 attiny824, attiny826, attiny827,
 attiny1624, attiny1626, attiny1627,
 attiny3224, attiny3226, attiny3227.


Tested it against SVN master.

Let me know about any help needed to merge this.


Thank you,

Follow-up Comment #31, patch #9543 (project avr-libc):

Is it possible to cut the Gordian knot? This patch applies cleanly and works
perfectly - as far as I can tell from my testing. I see no reason why it's
necessary for it to be tangled up with these other long-standing issues. I
would imagine this patch could be applied, and a release made in a couple of
hours work.

Can we have this patch integrated and released? I have used it for a complex

Thank you Wasti !
One issue as you pointed out is community support. We do best what we can,
each person within their own area of expertise, but proper documentation and
promotion is always an issue.
* Also I recommend gcc 8.0.0 (very fist gcc8 release) for proper LTO (-Os,
smallest possible size) working, anything >gcc8.0.0 will lead to 30% increase
of binary (in some corner cases).* Spent a lot of time tracking down issues
(by tracking commits) with LTO across gcc8 then gcc9 up to gcc10 and now with
a list of commits/reverts I found hard even to raise the issue to the GCC
community.

Same problem here. It says "devtools/gen-avr-lib-tree.sh" cannot be found,
even if the file is right here. After some head scratching, I realized the
patch must be applied as level "-p0". Instead of "patch < avrxmega3-v10.diff",
it should be "patch -p0 < avrxmega3-v10.diff". I've successfully applied the
patch to SVN trunk r2551.

Be back with updated patch new dev support. Need to rewrite generator in
py3 for that. Will also include a  doc with the steps.

People here seem to have successfully used the patches here, but I seem unable

When I attempt to apply any of them to libc-2.0.0, I get lots of complaints

Follow-up Comment #14, patch #9543 (project avr-libc):

Cristian, hello.

I just tried to compile avr-libc svn2546 with patches from
avrxmega3-v6.diff.bz2. compiler gcc8.0.1 built for avr.

I get some errors which are at least partly from this patch.
I did not get any strange messages before this just some warnings.
Also the last time I built it without the patch it looked right.
 
Could you have a look at it?

[avr-libc-dev] [patch #9543] Add avrxmega3 devices.

[Balint Cristian]

Follow-up Comment #13, patch #9543 (project avr-libc):

The avrxmega3-v6.diff.bz2 includes a ATDF parser for AVR8X.


- The new parser addition does:
* Generates iotn*.h just from atdf schema.
* Parse only AVR8X family types (constrained in script).
* Adds few alieases (hardcoded) as older coding-style.
* Headers generated are functional the same as Atmel's 3.6.1.
* Parser license is BSD (the very avr-libc one).


- BTW, One of main difference BSD vs Apache would be that Apache license
grants patents (patents will not circumvent the license terms). But I am not
lawyer.

[avr-libc-dev] [patch #9543] Add avrxmega3 devices.

[Joerg Wunsch]

Follow-up Comment #12, patch #9543 (project avr-libc):

Mixing the licenses is doable, it's just a little cumbersome
since we need to LICENSE documents then at the toplevel.

If #b is not too much work, it would be my personally preferred
solution, as it makes us completely independent from Microchip.
They've chosen to distribute their own version of the headers
independently from us anyway.

[Balint Cristian]

Follow-up Comment #11, patch #9543 (project avr-libc):



* The Apache license on io*.h might expose a problem.


- Some possible solutions.

  a) Mchip/Atmel right now mixes BSD+Apache in their packages, so avr-libc
could do it too ? (not a lawyer).

  b) Make new headers from scratch based from docs. A simple one (no fancy
struct), just simple enumerations.


* I incline to choose #b, and i am willing to do the task if You all here
agree. Probably wise would be to have a common avr8x.h and some alias files
that adds extras for each particular devices.

Johann,

Uploaded avrxmega3-v5.diff.bz2 .

* Add _PROTECTED_WRITE_SPM in xmega.h (as per Atmel's upstream 3.6.1).

[avr-libc-dev] [patch #9543] Add avrxmega3 devices.

[Georg-Johann Lay]

Follow-up Comment #8, patch #9543 (project avr-libc):

There must still be missing something, at least _PROTECTED_WRITE_SPM.  Apart
from a build warning for a missing prototype, it's neither resolved by a macro
nor my a symbol:


$ echo 'int main(){}' | avr-gcc -xc - -Wl,-u,eeprom_write_block
-mmcu=attiny1616
/srv/local/gnu/install/gcc-8/bin/../lib/gcc/avr/8.0.1/../../../../avr/lib/avrxmega3/libattiny1616.a(eewr_block_xmega.o):
In function `eeprom_write_block':
eewr_block_xmega.c:(.text.avr-libc+0x80): undefined reference to
`_PROTECTED_WRITE_SPM'

[Balint Cristian]

Follow-up Comment #7, patch #9543 (project avr-libc):

Johann,


- Thank you for the quick review.
- I believe your proposed changes are fine.

* The task presented here is fairly easy to do, all basic ingredients are
Atmel's upstream stuff. Not sure why they are not collaborating with you guys.
They started to keep lots of changes on their own fork (their changes have no
logs or names).

* Perhaps migrating to a more collaborative platform like github would help
this project a lot.

* I attached outputs of a sample main() program for atn1616 target that looks
good to me [attiny16161-disasm.txt.bz2]. Cannot validate yet on real device
(waiting for real chip samples) .

* I am working on avrdude & USBASP-firmware too for support UPDI 
 too (is quite similar to TPI). As reference for UPDI there is
https://github.com/mraardvark/pyupdi, you probably already know that.

Follow-up Comment #6, patch #9543 (project avr-libc):

Thanks, I can build avr-libc now and a quick test looks good.

Regarding the changes to eewr_block_xmega.c, maybe it's clearer to
special-case the different NVM flavours instead of #define + #undef + #define
chains?

I allowed me to attach a respective patch as avrxmega3-v4.diff.bz2

Follow-up Comment #1, patch #9543 (project avr-libc):

> Changed files: [...] ChangeLog 

The delta to ChangeLog is not reasonable, too much lines affected.

Usually, ChangeLog is prone to conflicts as each push is touching it; hence it
might be more comfortable to supply it as plain text snipped and leave it out
of the patch.
