Dear all,
My raspberry-pi is crashing in g_vfs_done error 5 () when I'm trying to
copy data from the rpi (with dd) to my USB drive on UFS2
I can notice a high %system load ~100% on the rpi before the crash
Apparently people succeed to "fix it" by decreasing the speed of the USB
bus with sysctl hw.usb.ehci.no_hs = 1
But in my case I cannot set this sysctl. And I didn't succeed to fix it
with camcontrol
Can you guide me on my investigation to decrease the speed of USB ?
Thanks for your work.
Cheers,Aurelien
