Hi all,

1. How to build the vps-loopback application example alone.?

2. How to do clean & build the vps-loopback application example ?

I am getting the below error.

while using the command gmake -s loopback_target

#

Hi Gokul,

Do you have any modifications of the source code of the example?

HI Yordan,

I have done some few modifications for our customized board.

What is the right way to build vps example application ?

Thanks & regards

Hi Gokul,

I think the gmake command you use is correct, but it is possible that those warnings for implicitly declared functions could lead to some errors later when the application is being linked.

Were you able to build the example successfully without modifications?

Yordan

Hi Yordan,

After clean build it was working .gmake -s clean and then gmake -s loopback.

But I got one more problem
Cortex_M4_IPU1_C0: File Loader: Verification failed: Values at address 0x00000001 do not match Please verify target memory and memory map.
Cortex_M4_IPU1_C0: GEL: File: D:\ti\vsdkv212\ti_components\drivers\bsp_01_07_01_17\binary\bsp_examples_displayDss\bin\tda2xx-evm\bsp_examples_displayDss_m4vpss_release.xem4: a data verification error occurred, file load failed.

Thanks & regards

Hi Gokul,

Data verification error can occur if the DDR is unstable or if the memory where you are trying to write is powered off.
Can you check if you have mapped 0x0 to IPU RAM instead of IPU ROM.
If 0x0 is mapped to IPU RAM then check if the IPU RAM is accessible and whether you can write to it.

Rishabh
