I used the value shown at the beginning of this bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=911560#15 I've not tested other values.

Any news on proposing your bugfix to mainline u-boot, Dominique? Wiki page https://linux-sunxi.org/Olimex_A20-OLinuXino-Lime2#GMAC_quirks now updated to cover the knowledge shared here and other places I could locate. How did you reach the value "3" for the bugfix? Did you test multiple values or followed advice from somewhere and could confirm that it was an improvement? Reason I ask is that the only places I could find that specific value was at the wiki page and here in this bugreport, and (as I have now clarified) the information seems to not be well tested and is different from what Olimex use in their fork of u-boot. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private signature.asc Description: signature

It looks like a similar patches was submitted 4 years ago and the tests of this patch did not go as well as I experienced: https://lists.denx.de/pipermail/u-boot/2016-March/248498.html I'll search in u-boot archive for other threads All the best

Please submit a patch to upstream fixing this in the appropriate files in configs/*; I'd guess configs/A20-OLinuXino-Lime2-eMMC_defconfig and/or configs/A20-OLinuXino-Lime2_defconfig. Then I'll feel happier about backporting them to u-boot in stable and eventually can drop the patch... live well, vagrant signature.asc Description: PGP signature

I've tested together: - Debian's u-boot debian/2019.01+dfsg-7 with CONFIG_GMAC_TX_DELAY=3 tweak - Debian's stable partition (dated 2019-11) with Lime2 Rev G2 and rev K cards. In both case the installer starts fine, sets network correctly (with dhcp) and starts downloading packages. Because I have a crappy connection and no use for a Lime2 Debian/stable installation, I've stopped the tests at that point. All the best

I've seen only outgoing traffic at about 20 to 30 Mbytes/s through NFS for the rev. K board. As far as I recall, I had about 20-25 Mbytes/s with the rev. G2 board and the vanilla u-boot. > With which kind on low-level network wiring did you test the negotiated > mode - e.g. cross-over cable to another host or gigabit-capable switch? standard cable to a gigabit-capable switch. > Would be great if you could also test with patched u-boot in stable > Debian - so we can consider fixing this in a point release. I can easily test with a patched u-boot from stable with a Debian/unstable. Would that be helpful ? All the best Dod

That's quite helpful. Thanks! Even more helpful if you provide a bit more information (if possible): I guess you mean that the negotiated ethernet mode is 1G. What is the actual performance - i.e. which concrete transfer speeds is achievable, in each direction, for each board? With which kind on low-level network wiring did you test the negotiated mode - e.g. cross-over cable to another host or gigabit-capable switch? Would be great if you could also test with patched u-boot in stable Debian - so we can consider fixing this in a point release. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private signature.asc Description: signature

K Ethernet problem - No connection possible in > installer https://bugs.debian.org/911560 So I've applied the suggestion to build u-boot with CONFIG_GMAC_TX_DELAY=3 I can confirm that both LIME2 rev G2 and rev K boards have a working network with 1G speed with u-boot version debian/2020.01+dfsg-1 and the tweak above. For the record, here's the recipe to get a working network OlinuXino Lime2 rev. K : Setup u-boot source: - git clone https://salsa.debian.org/debian/u-boot.git - sudo apt build-dep u-boot In u-boot: - apply all debian patches: quilt push -a - run: make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime2_defconfig - edit .config to set CONFIG_GMAC_TX_DELAY=3 - build u-boot: make CROSS_COMPILE=arm-linux-gnueabihf- You should get a u-boot-sunxi-with-spl.bin file which is the bootloader to install on your SD card (see [1]) First backup your SD card - sudo cp /dev/$sdcard backup.img Then copy the bootloader: - sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/$sdcard bs=1024 seek=8 In both case, $sdcard is to be replaced with the block device file of your SD card. Hope this helps [1] https://linux-sunxi.org/Bootable_SD_card#Bootloader
