ERRWB630001: controller freezing in modification with hardware button and a large number of I/O modules connected
Affected devices
Wiren Board 6 rev. 6.3
Description
When three or more side I / o modules are connected, the controller hangs when the button on the case is turned on. Hardware watchdog does not help at the same time.
Reasons and detailed description
The MCP23008 and MCP23017 chips in the input-output side modules by default enable the INT pin in push-pull mode with high state.
The pin is initialized to the "open collector" mode later, when the wb-hwconf-manager module is loaded.
Therefore, three or more modules provide enough current to supply parasite power to the processor through the INT line on the side connector when the processor is turned off. Parasite power through GPIO lines can cause the I.MX 6ULL processor to hang and "latch" due to the hardware features of the I.MX 6 series.
Workarounds
Do not use the power button with more than 2 I/O modules
=Scheduled fix
Fixed in rev. 6.4
ERRWB630002: Impossibility to update from a USB drive when connected to terminal block A4
Affected devices
Wiren Board 6 rev. 6.3, 6.4, 6.4.1
Description
If the terminal block A4 of the controller is loaded with a voltage corresponding to the logic unit (i.e. voltage from 3V and above), the controller does not detect the USB drive with the firmware update.
Reasons and detailed description
The bootloader mistakenly configures the controller's first USB port in OTG mode. The operating mode of the USB port when it is controlled by the same leg of the CPU which is connected to A4 input.
Workarounds
When updating firmware via a USB drive, disconnect the wire from the A4 terminal or remove the entire terminal block.
=Scheduled fix
Fixed in loader since version 1.0.0. The bootloader update is made on request at the Wiren Board office, the update is not considered as a warranty case.
ERRWB650003: Unable to update from USB drive in revision 6.5
Affected devices
Wiren Board 6 rev. 6.5
Description
The controller does not detect the USB drive with firmware update.
Reasons and detailed description
The bootloader mistakenly configures the controller's first USB port in OTG mode. At the same time the operating mode of the USB port is controlled by the same leg of the CPU which is connected to A4 input.
Workarounds
When updating firmware via USB flash drive, a voltage between 5 and 30V must be applied to A4 terminal strip. For example, you can connect terminals A4 and W1 or terminals A4 and W2 with a conductor.
=Scheduled fix
Fixed in bootloader since version 1.0.0, in devices shipped after 2019-03-10. The bootloader can be updated on request at the Wiren Board office or remotely.
ERRWB600004: the inability to upgrade from some USB drives
Affected devices
Wiren Board 6 of all revisions
Description
The controller detects a USB drive with firmware update, but after pressing the button to confirm the update, the update does not occur. Errors are displayed in the debug console:
EHCI timed out on TD - token=0x2e008d80 EHCI timed out on TD - token=0xae008d80 EHCI timed out on TD - token=0xae008d80 Error reading cluster ** Unable to read file wb6_update_FACTORYRESET.fit ** Read failed: -1
Reasons and detailed description
The bootloader does not process the controllers of some flash drives that are unstable in a special way.
Workarounds
Use a USB drive of a different model.
=Scheduled fix
Fixed in bootloader since version 1.0.1, in devices shipped since 2019-04. The bootloader can be updated on request at the Wiren Board office or remotely.
