what's the proper procedure to manually load firmware/kernel modules?

Hongfeng Wang

I am trying ubuntu12.04 armhf on DM8148EVM, so I have to manually load all the TI modules(EZSDK5.04)

This is what i did

insmod syslink.ko
sudo firmware_loader 1 /usr/share/ti/ti-media-controller-utils/dm814x_hdvicp.xem3 start
sudo firmware_loader 2 /usr/share/ti/ti-media-controller-utils/dm814x_hdvpss.xem3 start
sudo modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 i2c_mode=1

this is where the error starts:
notify_send_event failed! status = 0xfffffff0
notify_shm_drv_sendevent failed! status = 0xfffffff0
notify_send_event failed! status = 0xfffffff0
notify_shm_drv_sendevent failed! status = 0xfffffff0
notify_send_event failed! status = 0xfffffff0
notify_shm_drv_sendevent failed! status = 0xfffffff0
notify_send_event failed! status = 0xfffffff0
VPSS_CORE : Failed to init fvid2 interface,
vpss: probe of vpss failed with error -22
VPSS_CORE : failed to register ti81xx-vpss driver

Did i miss anything? the kernel command line i used:

--no-log rootflags=barrier=1 console=ttyO0,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ti814xfb.vram=0:16M,1:16M,2:6M ip=192.168.1.169:192.168.1.1:192.168.1.1:255.255.255.0::eth0:

Please help!

another thing that might be related:

when I run prcm_config_app on stock rootfs, it will display version number, and all the stuff.

But on ubuntu rootfs, it just exit silently without any output.

maybe this is compatibility issue, I am trying to recompile it with different -march flags

ldd prcm_config_app
not a dynamic executable

file prcm_config_app
prcm_config_app: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped

I am not quite sure about this, but I guess the codesourcery tool chain in not compatible with armhf.

So I am giving up this idea of armhf, trying ubuntu11.10 armel next.

Hi,

Few things to I can suspect from this.

1. notifyk.vpssm3_sva=0xBF900000 is correct as mentioned.

2. Are you trying this on 512MB board or 1G board. Mostly i think you are trying this on 512MB DDR board. In this case you need to change EZSDK memory map.

Thanks for the replay, Hardik.

I think it's just the rootfs compatibility. Now I am running ubuntu11.10 armel. the ti sample applications so far are working fine.

For those who are interested, I downloaded the preinstalled ubuntu image for omap3 from here:

Hi,

I am not getting correctly. Are you trying to say that rootfile system which you were mounting was not correct. And because of this you were seeing this errors.
