The drive mounting bracket in this unit acts has a heatsink for the CPU. There are 3 phillips screws on the back of the box which secure the cover.The first thing you’ll see inside is the hard drive. In my U-verse fiber installation the DVR is connected to the AT&T gateway via ethernet.Unlike most of other cable boxes I’ve disassembled the VIP2250 requires only a screwdriver to remove the cover.
Main Circuit BoardRemoving the three screws holding the hard drive mounting bracket in place exposes the main board.The main chip on the board is the Broadcom BCM7405DFKFEBB01G. If you are using an IR extender with this box you should place the infrared transmitter near this location. Just to the right of the record LED is the IR receiver.
UART Serial PortNear the lower right side of the board I discovered a 5 pin header labeled UART. Mediaroom is a complete IPTV delivery platform which is very popular among cable companies. Much more detailed information about this chip can be found in the schematic diagram.The chip is designed to support Ericson Mediaroom (formerly Microsoft Mediaroom). The chip has an onboard DDR2 memory controller and support for two SATA-2 storage interfaces.The BCM7405 product brief contains a general overview of the features supported by this chip.
Att Vip2250 Serial Port To
I already had a RS-232 to TTL adapter on hand that I bought from TCNISO a long time a go.These adapters are fairly easy to build but the easiest solution is a prebuilt MAX232. The range can actually be anywhere between -3 to -25 and +3 to +25 respectively.This means that in order to connect an RS232 serial port to the TTL serial port on the VIp2250 an adapter must be used. In RS232 serial a logic high is a negative voltage (usually -13) and a logic high is a positive voltage (usually +13). In TTL serial the different between a logic high (1) and a logic low (0) is the different between VCC and 0 volts. The two types of serial differ at the hardware level. At this point I had enough information to start testing.Through some research I learned that the VIP1710 used a baud rate of 115200 so I suspected the VIP2250 would probably be the same (testing later confirmed this).The TTL serial used by most embedded devices is different than the RS232 port found on computers.
MIPS-standard software debugging with software breakpoints A pin header needs to be soldered onto the board before a JTAG cable can be connected though.A wealth of information regarding the EJTAG port can be found in the schematic diagram and the preliminary hardware data module documents. EJTAG PortThe main board also has a clearly labeled 14 pin EJTAG TAP port. I also tried several other key commands with no success.This leads me to believe that either I haven’t correctly identified the RX serial pin or the boot loader is not configured to allow an interrupt.If anyone has any thoughts on how to interrupt the boot loader please leave a comment. The article I found for the VIP1710 suggested that pressing CTRL + C would interrupt the boot loader but I wasn’t able to get this to work. The motorola boot loader then starts the Microsoft IPTV boot loader which then starts the Windows CE operating system.I was hoping it would be easy to interrupt the boot loader to get a shell but so far my attempts have been unsuccessful.
This drive provides about 170 hours of HD video storage. Internal Hard DriveThe VIP2250 contains a 500GB Seagate SATA hard drive (model ST3500414cs). Based on what I’ve read in the documentation it seems apparent that Broadcom’s BroadBand Studio program plays some role in the debugging process.If anyone is aware of a cheap USB EJTAG cable that supports the BCM7405 please leave a comment. The Broadcom documentation suggests using either the Wind River Vision Probe or the Green Hills JTAG. The EJTAG debugging facility is performed on one TP at a timeI haven’t done any testing to with the JTAG port yet so I cannot confirm it’s status.
Since the partitions are formatted with FAT the drive can also be accessed using Windows.The 126MB partition contains files for the operating system (Windows CE ). I was able to successfully mount all of the partitions on a Linux system and examine the files. File System Structure Vip2250 ManualThe hard drive contains 2 small FAT16 partitions, and one large FAT32 partition.
I would recommend using a hard drive specifically designed for DVR usage such as the 1TB Western Digital AV-GP drive. If you install a drive that is larger than 1TB you will need to follow the procedure on Slumbuddy’s blog to resize the size of the data partition so it is less than 1TB in size.Upgrading to a 1TB drive will increase the HD video storage capacity from 170 hours to about 380 hours. The only caveat is the DVR can only utilize up to 1TB of space. These SLC files appear to function as filesystem on top of a filesystem (Probably providing encrypted storage for the video).Another blogger has done some analysis on these files and came up with a procedure to upgrade the hard drive in the VIP1216.I have tested his procedure and I can confirm it also works on the VIP2250.
