Writing video data on external hard disk | TDA2x

Hello Bharat,

Can you please give more information about platform, VSDK config and whether SD is used with Linux?

Also for file write are you using NULL link?

Hi Prasad,

Attached is the config file for VSDK . Yes  SD is used with Linux?

Yes we are using NULL link. we are getting following error while using virtual address for payload:
