Hello Stefan,
Thank you for the quick response.
Yes, I've been following the parallel thread and I've made the necessary
changes in the "/repos/base/include/spec/imx6/drivers/board_base.h" file.
I've set the following values:
*UART_1_IRQ = 57,UART_1_MMIO_BASE = 0x021e8000,*
*RAM0_SIZE = 0x20000000,*
It turns out I was flashing it the wrong way. I've fixed it by drawing
insights from how Android is currently being flashed onto the device. I've
followed a similar procedure. After installing the bootloader, I've flashed
the Genode uImage (generated using RUN_OPT += --include image/uboot) onto
the device as per your advice. Flashing was successfully done. Upon booting
up, I got the following:

*** Warning - bad CRC or MMC, using default environment

fastboot is in init......flash target is MMC:3
wait usb cable into the connector!
So, I've tried to write the image at an address and have loaded it from
there. I've did the following in the uboot prompt:
MX6Q SABRESD U-Boot > ext2load mmc 3:1 0x30000000 uImage
Loading file "uImage" from mmc device 3:1 (xxd1)

Load Address: 10001000
Entry Point: 10001000
Verifying Checksum ... OK

It stops here (even after adjusting the *UART* settings before building the
image). I've also tried *UART1* *(0x02020000)*, *UART3* (*0x021ec000*),
*UART4* *(**0x021f0000**)* and *UART5 (**0x021F4000**) *with the same
interrupt values.
I've built the uImage for log (make run/log) and demo (make run/demo). I'm
facing the same issue.
I'm unable to find the source of the problem. Can you give me any leads on
the possible problems?
Thanks,
Kranthi
