Re: McASP Device Driver

I dont know on which device are you trying to use this. On dm648, c6452,dm6437,c6424 you can get the McASP driver as part of the BIOS PSP package from :- https://www-a.ti.com/downloads/sds_support/targetcontent/psp/bios_psp/index.html However, these do work with the audio codecs. thanks regards sathya

Re: Modifying pixels' values in FVID_Frame
Sivaraj R3406
Hi, Only frameBufferPtr of the following frame union in fvid.h is valid in DM6437. The other members like iFrm, pFrm etc are used in DM648 platform and hence are not initialized in DM6437 VPFE/VPBE driver. The reason for this is that DM6437 supports only interleaved format unlike DM648 VPORT which...

Re: How to get YUV420 video from EVM 6437
Sivaraj R3681
The driver supports only YUV 422 interleaved data format as supported by VPFE. You can't configure the driver to generate a YUV420 planar format. This conversion should be done in the application only!!

Re: Video frame shifting on DM648 EVM

Do you still see shifting in video when you change the input? What type of input are you changing - NTSC/PAL? When you change the input, do the standard change from NTSC to PAL or vice versa?

In your earlier communication you have mentioned that video shift occurs only if you change the input and that shifting doesn't occur when the same input is plugged in again. Is my understanding right?

Very strange!! Is it possible to read TVP5154 registers during video shifting (using external I2C bus?) and check whether the signal is locked on by the decoder or not? Meanwhile I will try to reproduce this error at my end. Do you see a vertical shift or a horizontal shift?

Re: #error NO CHIP DEFINED

The newer devices including DM6437 no longer have support by the chip support library (CSL), thus there is no CHIP_xxx definition for the DM6437. The CSL has effectively been replaced by the peripheral support package (PSP) which provides DSP/BIOS drivers and is included in the DVSDK software package...

Chris, Do you use TVP5154 decoder present in the DM648 EVM or use some other decoder to capture video from the camera? As quoted by Bernie Thompson, it could be possible that the decoder is not generating any clock or sync signals to the VPORT. What version of PSP drivers or DVSDK are you using...

Re: DM648 EVM video driver lockup

This version of PSP will handle overflow/underrun errors gracefully WITHOUT the intervention of the application. Though the application can register notification callbacks when these errors occur. To do so, the application has to use VPORT_CMD_SET_VINTCB IOCTL to register the callback. In case of...

Re: DM648 EVM video driver lockup

Currently I am wondering if there might be some DMA conflict. Our algorithm processes at 10 fps, while the application captures at 30 fps. So there are 3 FVID_exchange calls between calls to our algorithm. I noticed that the error always first happens on the FVID_exchange call directly after our algorithm...

Re: DM648 EVM video driver lockup

So after some serious debugging, I found that our software library was configuring an ACPY before the previous ACPY finished. This collision resulted in the stall in ACPY_wait, and it was also throwing the video driver for a loop. My theory is that the DM6437 and DM6446 both run slower, so on those processors...

Re: VPBE Interrupt Content (dm6437)
Sivaraj R3681
Erman, Some fact: The frame buffer register of VPBE/VPFE is shadowed - which means that this register is latched or used by the hardware at the time of VSYNC. So even though the driver programs the register, it takes effect only after the next VSYNC. Below description explains how the driver manages...
