IPNC not working on DM368-IMX036 Appro

gooch12

As I mentioned in another thread (http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/100/p/130560/467798.aspx#467798), I can't get IPNC 2.6.1 to build and run correctly on an Appro DM368-IMX036 camera.

When I build in the release configuration (using davinci_dm368_ipnc_defconfig_rel), the boot sequence ends at

Loading iSCSI transport class v1.1-646.<5>iscsi: registered transport (tcp)

and then there is no login prompt. If the camera's boa server is running, it does not respond to HTTP requests. See the console output below.

When I build in the debug configuration (using davinci_dm368_ipnc_defconfig_dbg), the boot sequence completes and I get a login prompt. The usual IPNC processes appear to be running (system_server, av_server.out, boa) but the boa server does not respond to HTTP requests.

I'm using the 2.6.1 package provided by Appro. If I install Appro's pre-built 2.6.1 binaries into the camera's flash, the camera works correctly and responds to HTTP requests. It seems like I must be doing something wrong when building or installing Linux or the root filesystem. How can I resolve these problems?

Thanks for the suggestion. Using the debug build, I removed the systenv.cfg file and rebooted the camera but it didn't help. The camera boots successfully but the boa web server does not respond to requests from Internet Explorer.

I have made some progress. Here are a few observations:

1. The document "IPNC Reference Design on DM36x, User Guide" says that one can build either a "release" build or a "debug" build (see step 13 in section 3.1.1). To build the release build, copy davinci_dm368_ipnc_defconfig_rel to davinci_dm368_ipnc_defconfig. To build the debug build, copy davinci_dm368_ipnc_defconfig_dbg todavinci_dm368_ipnc_defconfig. However, this is NOT correct. Appro told me to build with the version of davinci_dm368_ipnc_defconfig that was included in the published distribution package. If you compare the various versions of these files, the most significant difference is that the various SPI flags need to be enabled. These include CONFIG_SPI, CONFIG_SPI_MASTER, CONFIG_SPI_DAVINCI, CONFIG_SPI_DAVINCI_DMA, CONFIG_SPI_BITBANG and CONFIG_SPI_SPIDEV.

2. Appro also advised that to use an NFS filesystem, boot with a NAND-resident root filesystem and then mount an NFS filesystem during the boot sequence or later. To do this, copy the rcS.nfs file to rcS in the /etc/init.d directory. Edit the rcS script to adjust the mount command to refer to the IP address of the NFS server.

3. The only way I have successfully built a "release" configuration and booted it from NAND using a NAND-resident root filesystem is to use the root userid when unpacking and building the IPNC software. If I use a non-root userid, the kernel and root filesystem images result in a failed boot sequence, as described earlier in this thread. The documentation states that using the root userid is not necessary (see step 14 in section 3.1.1) but it seems to be necessary. It is insufficient to simply re-build everything as root. It must be installed as root and built as root. I have not determined why this is necessary.
