Hi,
I tried to boot an ipipe Kernel on an MX28 based board, but failed.
Below are the boot messages I got for the ipipe-core-3.5.3-arm-2
release:

Interrupt pipeline (release #2)
After that, nothing more happens. I have read the log output directly
from Memory after a reset (from __log_buf), since nothing is output
on the serial console.
I also tried top of core-3.5.7 tree, with the same result.
The clocksource of "0.032 MHz" looks very strange. Is this
correct? Does anyone successfully has booted ipipe-3.5.7 on
MX28?
Best regards,
Martin

Hi,
The MX28 port was made on 3.4, at the time of moving to 3.5, things
seemed to have not changed much. Indeed the 0.032 MHz clock is wrong.
But one change got lost: the change which made the timer use the xbus
clock instead of the 32k clock. This should probably be changed in the
dtb. But I do not see how the "timrot" clock frequency gets defined.
Regards.

Hi Gilles,
thanks to your quick answer I was able to get the kernel running
on my MX28 board. I add the following:
tq@easypad:~/ipipe$ git diff
diff --git a/drivers/clk/mxs/clk-imx28.c b/drivers/clk/mxs/clk-imx28.c
index 658581c..d0887d9 100644
--- a/drivers/clk/mxs/clk-imx28.c
+++ b/drivers/clk/mxs/clk-imx28.c
@@ -312,7 +312,11 @@ int __init mx28_clocks_init(void)
return PTR_ERR(clks[i]);
}
+#ifndef CONFIG_IPIPE
clk_register_clkdev(clks[clk32k], NULL, "timrot");
+#else
+ clk_register_clkdev(clks[xbus], NULL, "timrot");
+#endif /* CONFIG_IPIPE */
clk_register_clkdev(clks[enet_out], NULL, "enet_out");
clk_register_clkdev(clks[pwm], NULL, "80064000.pwm");
clk_register_clkdevs(clks[hbus], hbus_lookups, ARRAY_SIZE(hbus_lookups))
I have no idea, if it is possible to configured this in the
device tree. And if yes, how it is done. I looked around in the
kernel sources, but did not find anything helpful.
But anyway, the above fix seems to work for me :). Thank you
very much for your help!
Best regards,
Martin
