The only one remaining was wmt.usb.param=11:3, which enables the USB subsystem – as I was booting from a USB-attached ‘disk’.. You can effectively ‘remove’ U-Boot parameters by setting their values to <blank>: setenv … Continue reading →

Looking at all the U-Boot parameters, I had expected this to be a real pain, but … Continue reading →
In preparation for the (final!) arrival of the APC, I have been setting up a suitable serial console connection, via USB to a UART, and have tested it on the Raspberry Pi.. After remembering (from years ago..) that you have to connect TX to RX – and vice-versa – the serial console worked without a problem, but … Continue reading →
As the complete source code for the APC is still unavailable, and it seems that the ‘standard’ Android OS on the device does not include some sort of console, the only way to get control (at least of the boot process) would appear to be by using the UART port on the board, and a pinout / … Continue reading →
