[fpga-miniconf] Unable to download boot.bin over TFTP

[Marc MERLIN]

Seems that (LX P=arty C=or1k) $ ./scripts/build-qemu.sh does not copy
boot.bin to /srv/tftp/initrd.bin and then tftp fails?

mkdir -p build/tftpd/
cp build/arty_net_or1k//software/firmware/firmware.bin build/tftpd//boot.bin
+ EXTRA_ARGS+=("-gdb tcp::10001")
++ grep spiflash_model platforms/arty.py
++ sed '-es/[^"]*"//' '-es/".*$//'
+ SPIFLASH_MODEL=n25q128a13

It seems however that said server isn't configured right?
[pid 22066] sendto(3, "<29>Jan 15 14:35:48 atftpd[17187"..., 74, MSG_NOSIGNAL, NULL, 0) = 74
[pid 22066] open("/srv/tftp/boot.bin", O_RDONLY) = -1 ENOENT (No such file or directory)
[pid 22066] sendto(4, "\0\5\0\1File not found\0", 19, 0, {sa_family=AF_INET, sin_port=htons(7642), sin_addr=inet_addr("192.168.100.50")}, 128) = 19

/srv/tftp was empty. Was I supposed to symlink it to my tree?

Ok, I did this manually:
(LX P=arty C=or1k) saruman:~/src/fpga/litex-buildenv$ sudo cp build/tftpd/boot.bin /srv/tftp/boot.bin

This seems to help, now I finally have:
Reading value 0000bc00 fr MDIO PHY 00000000 REG 00000011
MDIO mode: 1000Mbps / link: up

I'm better now, but what's the correct fix?

Thanks,
Marc
