Box is only detected during first seconds of power on #198
Comments
Does that happen if you power up, then just wait and issue the first |
Ok I was mistaken, it isn't the power up or boot that's the trigger, it's the time after I let the tool off the FEL button (inside the audio jack). I presumed FEL mode stayed active once entered, but it seems it doesn't. Even though the box looks like it's in FEL mode and
The problem is, keeping the button pressed doesn't keep the valid FEL mode active indefinitely and it seems to cut off randomly. The cable I'm using is new, works perfect with adb/fastboot/MTP etc. Forgot to mention, I did add a udev rule, as recommended here:
I guess I'll try different commands when the mode is active to see if I can stop it from cutting off... tomorrow. |
So the proper BootROM FEL mode is "eternal", it just stays there until the board resets(!) or some commands are send. So it could be that something is flaky, and the board resets for some reason, which then re-enters the BROM and thus FEL mode. |
Unfortunately I'm not having any luck, the only commands that will work are the above ones, I tried booting a u-boot.bin but it won't have it. One time I got a "permission denied" when running the command without sudo so I've been trying it with sudo as well but it hasn't helped.
I've been trying to catch it at the right time but it isn't having it. |
When connecting my Allwinner H6 box, it's only detected by Sunxi for the first 5 or so seconds after power on.
At power on I get valid responses:
Any attempt after that gives:
After these errors, the device appears to be still in FEL mode (light is red) and
lsusb
shows the device is connected in FEL mode:Bus 001 Device 019: ID 1f3a:efe8 Allwinner Technology sunxi SoC OTG connector in FEL/flashing mode
.I'm stumped, I wonder if there may be any help for this?
