So I’m trying to clear the eMMC so I can install Linux to the eMMC. I think I’ve gotten it into booted into USB mode. I’ve pressed the button while plugging into the OTG port (USB closes to the end of the board), nothing comes up via HDMI on the screen. Continuing forward based on https://wiki.radxa.com/Zero/dev/maskrom, I see
[ 1450.447454] usb 3-2: USB disconnect, device number 9 [ 1450.763842] usb 3-2: new high-speed USB device number 10 using xhci_hcd [ 1450.915045] usb 3-2: New USB device found, idVendor=1b8e, idProduct=c003, bcdDevice= 0.20 [ 1450.915065] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 1450.915068] usb 3-2: Product: GX-CHIP [ 1450.915071] usb 3-2: Manufacturer: Amlogic
in dmesg and lsusb shows
Bus 003 Device 013: ID 1b8e:c003 Amlogic, Inc. GX-CHIP
So far so good. Get the
boot-g12.py installed, and run it with
radxa-zero-erase-emmc.bin from that same page. Runs and exits cleanly. When I unplug and plug back in, it boots up and I see the Amlogic logo, and then MBOX and Android boots the rest of the way up. Don’t see any kind of USB storage pop up, nothing.
Am I doing something wrong? Tips? Things to try?
EDIT: I do see, after applying the
radxa-zero-erase-emmc.bin, on the monitor a “staring USB”, scanning bus, and then
Hit any key to stop autoboot: 0, and I have nothing else on the screen. I don’t have any keyboard or anything hooked up.
EDIT2: Apparently hooking up Serial console did something, because now both in serial and on the monitor, I see it doing MMC erase, and it’s going through that process.
I do see a lot of these in my dmesg
[ 4325.493695] usb 3-2: reset high-speed USB device number 24 using xhci_hcd
And this is the output in the Serial console, with a spinner at the bottom and it’s stuck here at this, with the spinner spinning. Going to leave it running this way for a while on power, hopefully it finishes successfully and doesn’t just keep running forever.
