Hi all!

I have a problem with loading the firmware for HDVPSS.

I am using the dm814x device and want to load the binary file for the VPSS firmware.

I enter:

insmod syslink.ko

and then:

firmware_loader 2 /usr/local/share/.../dm814x_hdvpss.xem3 start

Then i get the messages:

FIRMWARE: Memory map bin file not passed
Usage : /usr/local/bin/firmware_loader <Processor Id> <Location of Firmware> <start|stop> [Location of Mem map bin file]
FIRMWARE: Default memory configuration is used
MemCfg: DCMM (Dynamically Configurable Memory Map) Version : 2.1.1.1

And then the system is stuck, and i have to reboot.

What happens here?

I have similar issue...any updates to this?

Or at least where can I find more info/source on the dm814x_hdvpss.xem3 module?

I know how to load xem3, are you saying that I need the latest dm814x_hdvpss.xem3 file?

I have pulled in ti814x_hdvpss_1G.xem3 from the 01_00_01_37 HDVPSS binary package. Should that resolve my issue?

Eric Williams,

The version of PSP (Linux LSP) and HDVPSS firmware are tightly coupled. The version of LSP that you are using determines the version of HDVPSS to be used.

Thanks,

I'm using the rowboat Android project on custom HW that does not have TVP7002 which is cause for hang. When I run install_mc_components.sh, I get a dm814x_hdvpss.xem3. If I replace this with the latest hdvpss.xem3 from EZSDK, will this problem go away?

Update the EZSDK your'e using. In the later versions of EZSDK, the ARM is not hanged when calling the SYSLINK IPC as you encounter. Just update to the latest EZSDK and it will solve you the problem.

Hi,

I think Android is on very old version of EZSDK + PSP. Its not updated to latest PSP and EZSDK.

Hi All,

JFYI. The rowboat Android uses EZSDK ver 5_02.

I haven't seen this problem with ezsdk ver 5_03 when I migrated to ezsdk ver 5_03. However hw decoder stopped working which was fixed by little changes in the libstagefright framework.

What all is included in "migrating" to ezsdk ver 5_xx?

When I replaced the dm814x_hdvpss.xem3 with the one from ezsdk 5.04, the firmware loaded without hanging but when I tried to write to /dev/fb0 the response was:

ti81xxfb ti81xxfb: fvid2 create failed.

/dev/graphics/fb0: cannot open for write: Invalid argument

When I load the ti81xxfb.ko module, the dmesg responds with:

PM: Adding info for No Bus:fb0
<7>PM: Adding info for No Bus:fb1
<7>PM: Adding info for No Bus:fb2

Do you know what else I need to replace?

Hi,

I think you are missing VRAM=50M,in your bootargs.

0 Eric Williams over 13 years ago in reply to HardikShah

I changed bootargs from VRAM=16M to VRAM=50M

That didn't help.

Hi,

You just cant change binaries. Bootargs for the EZSDK binary and binary which is provided with PSP release will be different, please make sure that you have changed bootargs required for the EZSDK5.04

What steps are required to migrate the rowboat Android project from EZSDK ver 5_02 to 5_03?

Is there a wiki out there somewhere?
