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.
