youxiaojie,

There is no new u-boot for it. But the kernel is supported:

Quote

Linux Kernel 4.10.0 Kirkwood package and rootfs (Flattened Device Tree) for GoFlex Home/Net, Pogoplug E02/Mobile/V4, iConnect, Dockstar, Sheevaplug, NSA320, NSA320S, NSA325, NSA310S, NSA310, Topkick, Netgear Stora, ASUS-M25, Iomega ix4-200d, QiZhiTong 501mv2, HP Thin Client T5325, LG N1T1, Linksys EA4500, Lenovo/Iomega ix2-ng, and all other Kirkwood plugs that are already in the mainline.

Here is the working thread by wacke.

I looked the post first and then got a hardware. I hope to know why the uboot could not to be update? what is your opinion? I decide to connect an jtag using raspberrypi with openocd. do you agree wacke's view that the hardware crc or limit to change uboot? I don't think so.
by the way, to change baudrate of ttl port, the only way is to flash? the setenv baudrate seems unusable. the connexion is lost when accept the prompt "do you change baudrate"? There's no way to run saveenv. this occurred on Qizhitong. The reason I hope to change baudrate is kwboot using 115200 is uploading firmware whereas 9600 false, but terminal will not show correct. but terminal using 9600 shows ok 115200 bad.:)
your advice?

I also have a similar device using chip 88e6171 switch chips, does your kernel support this chips? or I must modify dts files to support this chips?

youxiaojie,

It should be possible to upgrade u-boot. I just never have time to look into it.

JTAG is overkill. You just need serial console like wacke did (or did he?).

> your advice?

I don't recall any problem with saveenv in wacke's working thread. Is the savenv command unavailable? or what else did you see when you try to save envs?
