Hi !
I always have this error:
VPSS_GRPX : please open fb0 node first.
Here are the different version used:
EZSDK: 05.02.02.60
PSP: 04.00.01.13
SYSLINK: 02.00.02.80
GRAPHICS_SDK: 04.05.00.02
Before sending this message i recompile every package, so it is not a version/compilation error.
Here is my bootargs:
dhcp;
setenv bootcmd 'run addip;tftp 81000000 uImage;bootm';
setenv hostname KDS01;
setenv addip 'setenv bootargs ${bootargs} ip=${ipaddr}:${nfsserver}:${gatewayip}:${netmask}:${hostname}:eth0:off';
setenv autoload no;setenv nfsserver 190.9.200.197;
setenv bootargs 'console=ttyO2,115200n8 root=/dev/nfs nfsroot=190.9.200.197:/home/banc_dt_078/targetfs,nolock rw mem=128M rootdelay=4 notifyk.vpssm3_sva=0xBF900000 vram=50M ti816xfb.vram=0:16M,1:16M,2:6M';
setenv serverip 190.9.200.197;
saveenv
I checked at target startup with lsmod that nothing is loaded.
Then i execute this instructions:
insmod /temp/vpss/04.00.01.13/syslink.ko TRACE=1 TRACEFAILURE=1;
/usr/share/ti/ti-syslink-examples/slaveloader_release startup VPSS-M3 /temp/vpss/ti816x_hdvpss.xem3;
### CAUTION: I don't know why but previous instruction failed, to solve the problem i start VPSS, then unload it ###
/usr/share/ti/ti-syslink-examples/slaveloader_release start VPSS-M3;
/usr/share/ti/ti-syslink-examples/slaveloader_release unload VPSS-M3;
/usr/share/ti/ti-syslink-examples/slaveloader_release startup VPSS-M3 /temp/vpss/dm816x_hdvpss.xem3;

The bold instructions give the following warning:
VPSS_GRPX : please open fb0 node first.
and a fbset -s -v -/dev/fb0 give:
root@dm816x-evm:~# fbset -s -v /dev/fb0

I really don't understand what is wrong, do you have a clue ?
Please help !
