<div dir="ltr"><div>Hi all,<br><br></div>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.<br><br>Starting kernel ...<br><br>kernel initialized<br>Genode 14.11<br>int main(): --- create local services ---<br>int main(): --- start init ---<br>int main(): transferred 511 MB to init<br>int main(): --- init created, waiting for exit condition ---<br>undefined instruction<br>[init -> platform_drv] --- i.MX6 platform driver ---<br>[init -> fb_drv] Starting i.MX6 framebuffer driver<br>[init -> test-framebuffer] --- Test framebuffer ---<br>[init] child "platform_drv" announces service "Platform"<br>[init -> fb_drv] Could not open file "config"<br>[init -> fb_drv] Could not obtain config file<br>[init -> platform_drv] void Ccm::ipu_clk_enable(): Enabling IPU Clk<br>[init -> platform_drv] void Iomux::ipu_enable(): Enabling IOMUXC Clk<br>no RM attachment (faulter 142090 with IP 10001e94 attempts to write to address 1280028)<br>void Genode::Pager_object::unresolved_page_fault_occurred(): not implemented<br>unknown signal context <br clear="all"><div><div><div><div class="gmail_signature"><div dir="ltr"><div><div><br></div><div>As
the trace shows after the init process creation one error "undefined
instruction" has been reported ? what could be the root cause of this ?<br><br></div><div>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 ?<br><br></div><div>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. <br><br></div><div>Next, I am getting the no RM attachment error and page fault. what could be the reason of getting this error? <br> <br></div><div>Thanks in advance.<br>Regards<br><br></div></div></div></div></div></div></div><div class="gmail_extra"><div><div class="gmail_signature"><div dir="ltr"><div>Chirag Garg<br></div>IIT Madras , Rise Lab<br></div></div></div>
