Re: mt760lu_mcu_wait_resp retrying

Power issues can be caused not just by a PSU that cannot supply sufficient current, but also if the cable connecting the PSU to the Pi is too thin. In this case as the current increases the voltage drop over the power cable will increase and can cause power problems. A similar issue can be caused if...

Re: Just burned out two pi zero boards

Really, are you sure?? On my Pi Zero the ACT LED is usually ON and flashes OFF when there is SD Card activity. Yes Try turning it on without an sd-card and the LED will not turn on! Obviously, but with an SD card with Rasbian running the LED is permanently on unless the SD card is being written to ...

Re: mt760lu_mcu_wait_resp retrying

I expect /etc/modprobe.d/81922cu.conf is not going to do anything useful. /etc/modprobe.d/8192cu.conf , without the extra 2, is usually used by the 8192cu driver and you are using the mt7601 driver. A couple of things I can think of - a possible power supply issue, or the motor driver interfering wi...

The rpi-update command loads the Testing branch kernel and firmware, which may by buggy or unstable. Unless you actually want to test possibly buggy and unstable software to report errors, don't rpi-update.

Re: rpi-update error

Had a look at rpi-update and found this line in the code

Code: Select all

SKIP_SDK=${SKIP_SDK:-0}
Added SKIP_SDK=1 to the rpi-update command and the error no longer appeared. e.g.

Code: Select all

sudo SKIP_SDK=1 rpi-update
Would be helpful if someone can explain the initial issue I had with the sdk directory not existing.
