Updated avrxmega3-v12.diff.xz:
  * Update wdt.h, sleep.h (based on avr8-toolchain-3.6.2.1778).

Thanks,
~Cristian.

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

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,
~Cristian.

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.

What would it take to get all these changes merged?

This patch is best integrated after the changes from


https://savannah.nongnu.org/bugs/?49567

and

https://savannah.nongnu.org/bugs/?57071

which will greatly reduce the number of conflicts.

Can we have this patch integrated and released? I have used it for a complex project on the ATtiny416, and have found no issues.

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.

  • Updated avrxmega3-v10.diff.xz with latest AVR8X devices.
  • Rebased on *.ATDF (AVR8X only) from latest:

     Atmel.ATtiny_DFP.1.4.310.atpack
     Atmel.ATmega_DFP.1.4.351.atpack

  • Header generator updated to python3
  • Update FUSE generation in header (as per original *.h)
  • New devices:

     atmega808,atmega809,
     atmega1608,atmega1609,
     atmega4808,atmega4809

  • GCC 9.3.1 is needed for newer devices

I too have successfully used this patch to add support for ATtiny814 to my avr-libc. Can it be considered for mainline merging sometime please? This would help improve the uptake of these new chips.

I have successfully used this patch with the ATtiny817 which works well. Are there concrete plans to get this merged?

The python header generator still generate 1:1 as upstream. Validated against latest (9/28/2018) avr8-gnu-toolchain-3.6.2.1759-linux.any.x86_64.tar.gz by DIFF-ing, and difference is cosmetic only.

Cristian,
That compiles fine but for some warnings.

Unfortunately I am not in a position to test the set up. I am building an Ada toolchain. I guess little of this stuff will be used, since I make Ada spec files with the MCU specifics.
But if you have some piece of program and tell me howto I will gladly compile and see whether the generated code makes sense or not.

You might also want to tell me what to do about some of the warnings, then I will patch for it.
This is the most annoying one:


../../../include/ctype.h:112:1: warning: ignoring attribute 'const' in declaration of a built-in function 'isgraph' because it conflicts with attribute 'pure' [-Wattributes]
 extern int isgraph(int __c) __ATTR_CONST__;
 ^~~~~~
<built-in>: note: previous declaration here


ctype.h is full of them.

Enjoy your Easter holiday.

j.

Jan,

  • Can try v7 of patch ?


  I missed a # sign in header generator, included a fix for generator and also reincluded generated header files. It was my mistake during assamble of V6 patch.

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?

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.

 Balint Cristian <cbalint>
Fri 19 Jan 2018 10:42:09 AM UTC, comment #12: 

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.

  • 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.

Thu 18 Jan 2018 04:32:53 PM UTC, comment #10: 

Ok, better now.  At least the trivial example builds now.

Some final notes on xmega.h:

Constraint "d" for [ccp_ioreg] resp. [ccp_spm_mask] could be relaxed to the less restrictive "r".

And from a strict point of view, both _PROTECTED_WRITE and _PROTECTED_WRITE_SPM are clobbering memory.

 Georg-Johann Lay <gjlayde>
Thu 18 Jan 2018 03:53:50 PM UTC, comment #9: 

Johann,

Uploaded avrxmega3-v5.diff.bz2 .

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


Balint Cristian <cbalint>
Thu 18 Jan 2018 03:10:27 PM UTC, comment #8: 

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

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.

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

Johann, Joerg,

  * Attached avrxmega3-v2.patch.bz2 to add ChangeLog as new file.

Wed 17 Jan 2018 04:12:13 PM UTC, comment #2: 

I agree with Johann's comment regarding ChangeLog, though it's
not too hard to simply extract the text from the diff.

It might be the first commit in 2018, so it's going to be a
completely new ChangeLog file anyway.

> 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.

Georg-Johann Lay <gjlayde>
Wed 17 Jan 2018 03:29:03 PM UTC, original submission:
