Hi all,
I am trying to run available os/run/framebuffer.run script on imx6 platform with modification for imx6. I am getting the following trace on the execution.
Starting kernel ...
kernel initialized Genode 14.11 int main(): --- create local services --- int main(): --- start init --- int main(): transferred 511 MB to init int main(): --- init created, waiting for exit condition --- undefined instruction [init -> platform_drv] --- i.MX6 platform driver --- [init -> fb_drv] Starting i.MX6 framebuffer driver [init -> test-framebuffer] --- Test framebuffer --- [init] child "platform_drv" announces service "Platform" [init -> fb_drv] Could not open file "config" [init -> fb_drv] Could not obtain config file [init -> platform_drv] void Ccm::ipu_clk_enable(): Enabling IPU Clk [init -> platform_drv] void Iomux::ipu_enable(): Enabling IOMUXC Clk no RM attachment (faulter 142090 with IP 10001e94 attempts to write to address 1280028) void Genode::Pager_object::unresolved_page_fault_occurred(): not implemented unknown signal context
As the trace shows after the init process creation one error "undefined instruction" has been reported ? what could be the root cause of this ?
I changed the all platform_drv files according to imx6. which seems to be working from the "child platform_drv announces service Platform " message. Is any thing wrong here ?
After this i am getting the error "could not open file config". I read other mailing list thread which says it is not an error but while tracing the code of framebuffer. I feel that it is important for framebuffer. But still i am not able to find the location where to put config file and what will be the content of this file.
Next, I am getting the no RM attachment error and page fault. what could be the reason of getting this error?
Thanks in advance. Regards

Hi all,
I was trying to understand the flow of framebuffer flow for given imx53 code in the following directory repos/os/src/drivers/framebuffer/imx53/main.cc
In the main function, one static variable "session_component" has been created which uses the "config_attribute" function defined in line number 115 which expect a config file in build process.
What is the need of this config file with respect to framebuffer and where should i found this config file in the repository because when i run the framebuffer script it is not able to open config file?
