5MP problem

umair khan

Hello,

I want to get 5MP image from DMVA2IPNC-mt5 (any format). I reduced the kernel memory to 30MB (phys_start=0x81e00000), but to no avail. I am using following bootcmd & bootargs:

setenv bootcmd 'tftpboot 0x80700000 uImage_ipnc_DMVA2;bootm 0x80700000'

setenv bootargs 'console=ttyS1,115200n8 noinitrd rw ip=192.168.1.168:192.168.1.20:192.160.2.1:255.255.255.0:::off root=/dev/nfs quiet nfsroot=192.168.1.20:/home/umair/IPNetCam/ipnc/target/filesys,nolock mem=30M'

When I try to set the 5MP at prompt (./av_server.out DM368 RTSP AEWB APPRO2A 5MP MJPEG 5000000 VBR AUTO MENUOFF &), I get following error:

CMEM Error: allocHeap: Failed to mmap buffer at physical address 0x84140000

CMEM Error: Freeing phys buffer 0x84140000

I suppose after reducing linux memory to 30MB, there should be enough memory of supporting 5MP.

I will really appreciate any help in this regards.

Regards,

Umair

what are the arguments you are providing while inserting cmem module?

Hi,

The arguments are :

insmod cmemk.ko phys_start=0x81e00000 phys_end=0x88000000 allowOverlap=1 phys_start_1=0x00001000 phys_end_1=0x00008000 pools_1=1x28672

insmod edmak.ko

insmod irqk.ko

insmod dm365mmap.ko

I think this is what you are asking for. I just reduced the phys_start address from default (0x83000000 for mem=48M) to 0x81e00000 (for mem=30M).

Hey,

I keep using a script for my dm365 to insert cmem module with requirement for pools =4x4667200 [yuv/bayer files of size 1920x1080]. I just copied its content here. Try this. I used 60M for kernel. This works without any hassles for me.

# Default Memory Map
#
# Start Addr    Size    Description
# -------------------------------------------
# 0x80000000    60 MB   Linux
# 0x83C00000    68 MB   CMEM

# This loadmodules script is provided to support 1920x1080 resolution file based

# Sample bootargs is given below
# mem=60M console=ttyS0,115200n8 root=/dev/nfs rw nfsroot=<nfsroot> ip=dhcp vide

# Pools configuration
insmod cmemk.ko phys_start=0x84c00000 phys_end=0x88000000 pools=4x4667200

Hi Nagabhushana,

My problem is not 1920x1080 resolution. I can work fine up to even 3MP resolution. The problem occurs only in 5MP resolution. Will it work for 5MP?

ok. what is the width x height of the image you are trying to capture?

2592 x 1944 (or near to it).

Nagabhushana,

If you have any idea about how to get this resolution, please let me know. I have tried out everything and I am now about to assume that perhaps I can never get 5MP resolution from this camera.

Umair,

I thought issue was with cmem module initializing, so tried help from that end. Since the query is about IPNC softwares support for 5MP, I leave it to IPNC experts to answer.
