Boot from nand
Kernel 3.4 was the last known version supporting NAND boot. Since its deprecation nearly a decade ago, equivalent NAND support has not been integrated into mainline kernels. -

poor network performance / send only
Hi, looks like the issue still persists, but I have a temporary solution in case if your upload speed drops *way* beyond yours (2 Mbps for me). You can force-use a 100 Mbps link speed. `iperf3` results below. Literally 50x speed increase in my case! I've performed these benchmarks connecting to my VPS via wireguard: ``` $ cat /dev/mtd/by-name/U-Boot | strings | grep -B1 "u-boot,version"` U-Boot: 2026.01_armbian-2026.01-S127a-Pc2e6-H706e-Vab81-B2eb2-R448a ``` Linux 6.18.10-current-rockchip64 Standard operation (1000 Mbps): ```root@odroidm1 ~# ethtool -s eth0 speed 1000 duplex full root@odroidm1 ~# iperf3 -c 10.0.3.1 Connecting to host 10.0.3.1, port 5201 [ 5] local 10.0.3.2 port 42538 connected to 10.0.3.1 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 384 KBytes 3.14 Mbits/sec 5 14.7 KBytes [ 5] 1.00-2.00 sec 384 KBytes 3.15 Mbits/sec 5 6.68 KBytes [ 5] 2.00-3.00 sec 384 KBytes 3.14 Mbits/sec 2 13.4 KBytes [ 5] 3.00-4.00 sec 256 KBytes 2.10 Mbits/sec 6 9.35 KBytes [ 5] 4.00-4.43 sec 128 KBytes 2.42 Mbits/sec 0 22.7 KBytes ``` Dirty fix, link capped at 100 Mbps at most: ``` root@odroidm1 ~# ethtool -s eth0 speed 100 duplex full root@odroidm1 ~# iperf3 -c 10.0.3.1 Connecting to host 10.0.3.1, port 5201 [ 5] local 10.0.3.2 port 42354 connected to 10.0.3.1 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 11.4 MBytes 95.3 Mbits/sec 0 1.03 MBytes [ 5] 1.00-2.00 sec 10.5 MBytes 88.1 Mbits/sec 0 1.03 MBytes [ 5] 2.00-3.00 sec 11.4 MBytes 95.4 Mbits/sec 0 1.10 MBytes [ 5] 3.00-4.00 sec 10.2 MBytes 86.0 Mbits/sec 0 1.10 MBytes [ 5] 4.00-4.48 sec 5.00 MBytes 87.4 Mbits/sec 0 1.10 MBytes ``` So.. yeah. While using Wireshark I also saw *a lot* of TCP retransmissions too, which usually don't happen that at 100 Mbps link in my configuration. -

ESPRESSObin Firmware/Bootloader
Hi @KV1 looks like you are hitting this issue: https://github.com/MarvellEmbeddedProcessors/A3700-utils-marvell/issues/35 As you can see, Marvell is not very active in these repos. So you have two choices: 1) use older binutils/gcc (probably the easiest option), or 2) fix the issue with the source code. The fixes I'm seeing look simple enough to implement, and I will likely need to include them in the future when/if I update the github runners used to build releases.

"Armbian Imager" installation fails due to access rights for Microsoft Edge under Windows 11
Thanks a lot for all responses to my query. I'm afraid I haven't had the time to tinker on this issue long enough to find a solution. However, as I don't need to use Armbian Imager that often. So I can live with those rare cases of starting Windows as admin and running the program as such.
