Hi all,
I wanted to give a short status update on the MTK platform, I spent the last day implementing a minimal subset of the MTK romloader protocol in osmocon.
We can now run our own C-code on the MT622x, I started by modifying the linker script and run proms loader (because it doesn't need interrupts, the interrupt redirection isn't yet figured out).
When writing something to the UART TX register, I see the output in osmocon, and writing to the Baseband powerup register works as well (otherwise you would have to hold down the power-button all the time).
Unfortunately there are no schematics for the Mobistel phone I've been testing this with, so I haven't found out how to enable e.g. the backlight, nothing happens when activating PWM1/2.
Today I tried to modify the Calypso UART driver for the MTK UART, but currently I'm stuck with a strange hang somewhere in the driver, maybe I'll look after it tomorrow.
That was it for the moment...
Regards, Steve
