Problem with unbricking, will not make to usb mount media

[Amatrelan]

Classical error and forgot to take ssh password up before starting to toy with rM2...

Well now when I try to unbrick with this guide for some reason I cannot make it to USB Mass Storage device detected state.

I have pogo connection as described and other connections too. Tested with multimeter that resistance is correct and other things too (there was little variance on resistor batch I have, so might be that it's the problem but 10.02k...)

Well now to the logs I have:

[ 2771.537305] hid-generic 0003:15A2:0076.0025: hiddev97,hidraw7: USB HID v1.10 Device [Freescale SemiConductor Inc SE Blank ULT1] on usb-0000:03:00.0-7/input0 [ 2831.535253] usb 1-7: USB disconnect, device number 69 [ 2832.898015] usb 1-7: new high-speed USB device number 70 using xhci_hcd [ 2833.107290] usb 1-7: New USB device found, idVendor=15a2, idProduct=0076, bcdDevice= 0.01 [ 2833.107294] usb 1-7: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2833.107296] usb 1-7: Product: SE Blank ULT1 [ 2833.107297] usb 1-7: Manufacturer: Freescale SemiConductor Inc [ 2833.126303] hid-generic 0003:15A2:0076.0026: hiddev97,hidraw7: USB HID v1.10 Device [Freescale SemiConductor Inc SE Blank ULT1] on usb-0000:03:00.0-7/input0

It seems to disconnect quite frequently automatically and reconnects, never found out the reason it does it, as you can see it's already on 69 and going up. Never found out reason it does this. I tried multiple different cables and micro-usb breakout board but nothing fixed it.

Also it seems to my eyes that imx_usb is run correctly:

config file <.//imx_usb.conf> vid=0x15a2 pid=0x0076 file_name=mx7_usb_work.conf config file <.//mx7_usb_work.conf> parse .//mx7_usb_work.conf Trying to open device vid=0x15a2 pid=0x0076 Interface 0 claimed HAB security state: development mode (0x56787856) == work item filename u-boot-ums.imx load_size 0 bytes load_addr 0x00000000 dcd 0 clear_dcd 0 plug 0 jump_mode 3 jump_addr 0x00000000 == end work item header_max=10400

loading binary file(u-boot-ums.imx) to 877effd4, skip=0, fsize=9f02c type=aa

<<<651308, 651308 bytes>>> succeeded (security 0x56787856, status 0x88888888) jumping to 0x877f08e4

But still it won't show as mountable device (lsblk). But I noticed it disconnects after imx_usb but it won't connect as bootable, only reconnects to "old" way.

So if someone can point out right away whats wrong, I'm happy to listen.

also is in this stage if the device does not start on its own, press the Power Button meant to show up "Remarkable is booting" text on screen or just device showing up in lsusb / dmesg, if it means that remarkable text then I have some problem cause while usb-c breakout board is on it won't boot at all on that state.

after you see Freescale etc, you should remove the B8 short, before you run ./imx_usb

[Amatrelan]

Yeah I remove it, but it still does that "hard" reboot thing after running imx_usb.

So I did correct but seems to be that there is something else funky going on.

the cable pogo connection is not stable then

[Amatrelan]

Ok, seems to be that in my re2 there is some problem in pogo pins, on my friend re2 same setup works perfectly and no problems at all.. well seems to be that my re2 gets upgraded from digital paper to paper weight.
