Hi Nikolay, I'm trying to port genode onto i.MX6. I cloned your work to see if it works on my MX6Q-sabrelite. I followed the following steps: 1. ./tool/create_builddir hw_imx6 BUILD_DIR=imx6 2. In imx6, I did a RUN_OPT="--target uboot" make run/printf 3. I transferred the uImage using tftpboot at 0x20000000 4. bootm 0x20000000 It reaches the "starting kernel" stage and gets stuck there.
I did a readelf to see if the address I chose overlaps the bootloader. It doesn't seem to. *Output:*
Entry point 0x10005d70
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Align
EXIDX 0x07dd3c 0x1007dd3c 0x1007dd3c 0x018a8 0x018a8 0x4
LOAD 0x001000 0x10001000 0x10001000 0x47fc0 0x47fc0 0x8000 LOAD 0x049000 0x10049000 0x10049000 0x39768 0x262c55 0x8000
Any pointers on where I'm going wrong?
Regards kaushik

Hello
Firstly, thank you for patiently replying to our queries and debugging issues so far.
We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues).
Here's a brief reboot of our attempt:
- edit create_builddir to add a rule for imx6 board and added
build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference)
Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site.
We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

Thanks and regards Aditya
Hello, four months ago I added basic support for i.MX6 to genode. Results of this work you can see at https://github.com/decaprox/genode/tree/i.mx6.
