Anybody knows the max resolution support for DM355 and how to get 5MP image capture using mt9p031 sensor with kernel 2.6.10 ?...
Plzzzzzzzz reply ASAP:)
I think you question about IPIPE limits. As example, on DM368 I send data via IPIPE twise for get 5 Mpx (2560x2048). IPIPE have limits in 2176 pixels width.
Hello Kirill Brilliantov
Thanks for your reply., But Im not using iPIPE. i was trying to capture image using v4l2 at 5mp resolution but i can get a max of 1280x720 (0.9mp) from my sensor. Can you tell me which all parameters should i change in driver file (mt9p031.c) or v4l2 to enable this resolution..?
IPIPE is a internal block, What stream from your matrix? I think RAW. TI codec can encode only YUV, you can't send data from sensor in codec.IPIPE can convert RAW to YUV, after this you can encode data.
Regarding this issue, one stumbling block is getting the 5MP image from the sensor into the vpfe block. The vpfe driver for DM355 (DVSDK 1.30) is structured for a max frame size of 1920x1080. Any buffer size above 4MB causes a crash at kernel init.
Moving to a new DVSDK where 5MP mode is available is on the cards, but in the meantime we have to try to get 5MP capture working on the older DVSDK. Any ideas on how to proceed?
