Regards, Karsten I will be testing your patch along with Hans' patch. In fact, I have already compiled it - I'm just waiting for a new SD card reader to arrive tomorrow. Sorry for the delay. In the mean time, as I was trying to get the device to boot at all (not related to u-boot, just my broken sdcard setup), I did try my old SD card again to load the debian netinstaller. This should be the version with the TX_DELAY set to 4. Now I'm sitting in an ash shell and I can wget files from my desktop at around 100MB/s. ~ # wget http://192.168.1.170:8000/debian-8.3.0-i386-netinst.iso -O - | md5sum Connecting to 192.168.1.170:8000 (192.168.1.170:8000) - 100% |*******************************| 315M 0:00:00 ETA 37f329724a1c072cbe0ebda211fdeb88 - ~ # wget http://192.168.1.170:8000/debian-8.3.0-i386-netinst.iso -O - | md5sum Connecting to 192.168.1.170:8000 (192.168.1.170:8000) - 100% |*******************************| 315M 0:00:00 ETA 37f329724a1c072cbe0ebda211fdeb88 - ~ # date +%s; wget http://192.168.1.170:8000/debian-8.3.0-i386-netinst.iso -O /d ev/null; date +%s 1258 Connecting to 192.168.1.170:8000 (192.168.1.170:8000) null 100% |*******************************| 315M 0:00:00 ETA 1261 ~ # dmesg | grep -i link [ 1.504918] audit: initializing netlink subsys (disabled) [ 88.561822] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 90.547368] sun7i-dwmac 1c50000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx [ 90.547424] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready ~ # cat /etc/lsb-release DISTRIB_ID=Debian DISTRIB_DESCRIPTION="Debian GNU/Linux installer" DISTRIB_RELEASE="9 (stretch) - installer build 20160316-00:13" X_INSTALLATION_MEDIUM=netboot ~ # uname -a Linux debian 4.4.0-1-armmp #1 SMP Debian 4.4.4-2 (2016-03-09) armv7l GNU/Linux It takes around three seconds (date +%s; time not set) to transfer the 315MB. The md5sum matches. Now, with the device sitting on my desk in a debian installer session and working gbit.. how do I proceed from here? I don't dare rebooting..
