Hi Phillipp,
hope things doing OK.
I recently update to the 3.12-rc kernel and hit this problem below.
[ 3.377790] coda coda-imx27.0: iram pool not available
[ 3.383363] coda: probe of coda-imx27.0 failed with error -12
I read your comments of the patch-set using platform data rather then
hard coded addresses to get
the ocram from a SoC.
I checked the imx27.dtsi for the iram (coda: coda@..) definition and
compare with the former hard coded address and size it matches.
My .config also has the CONFIG_OF set.
Any Idea what's go wrong?
do you have the mmio-sram driver enabled (CONFIG_SRAM=y)?
regards
Philipp
No, I didn't, and I found out that my device is not yet ported to use
"Device Tree Support"
for the moment I will quick add the CONFIG_SRAM and see what happen,
but on the long term I move my code (clone of mach-mx27ads.c)
to DTS which makes absolute sense when I see how nice that code works.
Thanks for the reply!
Chris
CONFIG_SRAM not solve my problem, I must port the code to Device Tree
Support and call the of_ functions to make the iram config available.
thank you.
Chris
