0350001: Insufficient peak current
Revision:
3.5
Description
In a small part of devices shipped before 10.06.2014, the power supply circuit incorrectly limits the output current.
Symptoms
- The Board sometimes reboots when you boot right after initializing the USB hub
- The Board reboots when GSM is running at a poor signal level.
How to fix
The current-setting resistor needs to be replaced. Contact technical support. See also 0350004
0350002: Intermittent shutdown leads to the impossibility of download
Revision:
3.5
Description
After a short (<1s) shutdown of the WB SH using the switch on the case, the device does not boot.
How to fix
-
Workarounds
Turn off the board for a few seconds, then turn back on.
Reason
Undocumented processor behavior.
0350003: Work with DMX512 is not supported
Revision:

How to fix
Need to replace the crystal oscillator, and recompile Device Tree/en. Recommended value: 24MHz.
Workarounds

Reason
The wrong value of the crystal oscillator.

Revision:
3.5, S/N before 230

If GSM is active and the signal level is poor, it can be observed under certain conditions:
- reboot the Board
- disable and reconnect the Wi-Fi module
- Ethernet shutdown
How to fix
Unsoldering capacitor C11 fixes the problem. See diagram.

Revision:
3.5
Description
Incorrect C5 capacitor value in a very small number of boards shipped before June 10, 2014.
Symptoms
There are problems with switching the Board on: the device turns on only after several switches of the on/off button.
How to fix
- Change the capacitor C5 to the capacitor of capacity 1 µf (see figure)
