STM32N6 Venc_server example with internal ram only

[Leggs]

Hi,

I am running the latest version of the VENC_SERVER application and am interested in the mode that uses no external memory. There is a define for 720p 30fps using internal memory only, but trying to compile it in debug mode results in a compile error with .bss data not fitting in memory.

Could anyone advise on how to change the example or linker script to get the internal memory only version working?

Thanks

Hello @Leggs 

I compiled the example VENC_RTSP_Server with CubeIDE. There is no compilation error for the debug mode.

What is the CubeIDE version you are using?

Hi,

I downloaded all the tools yesterday, so it should be the very latest. Using STMCube for N6 V1.3. The default configuration works fine.

My issue is specifically with selecting the FULL_720P_SLICE_INTER_RAM_ONLY mode in venc_h264_config.c

This attempts to place large video buffers in internal ram, but fails due to ram limits defined in the included linker STM32N657XX_LRUN.ld

Thanks
