Linux/TDA2: I copy some function codes form use-case and add into the others use-case. Error message : Faulty address is 0x4, called from 0x1b155.

Part Number:TDA2

Tool/software: Linux

Hi Sir,

My HW is TDA2x CPU board + Vision Board + daughter board + LVDS sensor and SDK is PROCESSOR_SDK_VISION_03_04_00_00 with TDA2XX_EVM_LINUX_ALL define.

I select use-case "4CH VIP LVDS capture + SGX MOSAIC + DISPLAY".

I want to save the source image in this ues-case, then I add some function code in this case (chains_lvdsVipMultiCam_SgxDisplay.c),

example "static Void mountFatFs()", "static Void saveCaptureFrames(chains_srvCalibration_DisplayAppObj *pObj)"....etc.

After boot on the EVK and select this use-case, it can't be executed successfully, console mode shows below error message:

****** Segmentation fault caught ....
Faulty address is 0x4, called from 0x1b155

 SI code = 1 (Address not mapped to object)
 Fault addr = 0x4
[bt] Execution path:

What does it mean?

Please help and thanks.

Ranny.
