Booting from USB on Lemote 8089a

Hello everyone,

I just bought a lemote yeeloong 8089a (yes I know its old, but I do like this particular lemote) and when I attempt to boot the system up from a usb drive, it just hangs at the lemote splash screen. I do see the usb drive flash several times, however i let the system sit for several minute (normally, its already booted up into GNU/Linux by that point) and nothing. Doesn't respond to any key combos neither (Del doesnt do anything, B doesn't do anything, tab doesnt do anything). I did upgrade the firmware to the latest available for this system (1.4.3) and no difference. USB works just fine, however, after booting the operating system. It does this with any USB drive I plug in. Is there anything I am doing wrong, or is this a known problem with the Lemote Yeeloong 8089a?

Thank you

看你的描述,应该是系统挂载参数有问题,根目录的挂载。将usb盘系统里的fstab的挂载参数修改好

thing is, I plug the usb drive in before powering on the computer, gets to the pmon firmware where it enumerates the USB bus and it appears to hang. I cant even boot into the operating system. I cant seem to get past the "USB step" in the lemote's power on self test. Also, I have tried this with both FAT and ext2 formats.

的是,我在通電之前在電腦上插入USB驅動器,得到它列舉了USB總線的PMON固件,它似乎掛起。我什至不能開機進入操作系統。我似乎無法讓過去的“USB”龍夢的開機自檢步驟。另外,我曾經嘗試這樣做fat和ext2格式。

Update: I was able to get it to boot from a USB Hard drive and a USB memory card reader. My guess (I have not yet looked at the logs) is that it is looking for a disk controller rather than a disk itself (the USB thumb drive I was using was just a flash chip and a USB chip and that was it, no distinct controller). THAT is an assumption and I could be wrong there, but the fact remains that I hooked up disk controllers with disks attached and it was able to read from them.
