http://www.mattmerry.com/blog MattMerry.com Thu, 19 Feb 2009 01:19:06 +0000 http://backend.userland.com/rss092 en With the three new sections decoded and a change I've made to the sections.txt file, I figure its time to share the code with whomever wants it. The updates in this version are: Parses CMbP Sections Parses CMbH Sections Parses CMbT Sections Adds support for identifying section by unique ID in secitons.txt Drops support for ... http://www.mattmerry.com/blog/2009/02/01/update-to-parsebin-and-sectionstxt So, the CMbT section is pretty easy as well. The section is basically comprised of a Title or variable name string and then the value. It appears that these are all some sort of test stings. There is one interesting lesson learned from CMbT sections. If you recall, in my ... http://www.mattmerry.com/blog/2009/02/01/cmbt-sections The CMbH Sections are pretty short and simple, so I'll just get to the layout. There are two interesting things to note in these very short sections. The section basically costains a String value and some other unknown, interesting value. Now sure what the number is, an offset, index, size, ... http://www.mattmerry.com/blog/2009/01/29/cmbh-sections-decoded I had some time over the holiday to dust off the SD14 firmware project. I was able to mostly decode the CMbP sections in the firmware. I'm not sure yet what they represent, but I'm able to understand most of the information in the section. First, lets look at the CMbP ... http://www.mattmerry.com/blog/2009/01/10/cmbp-sections-decoded There was this restaurant near work in Redmond called Bar Shu and man it was good. They closed down about a year after they opened, but they served authentic Chinese food, and they had this beef noodle soup called niu ro mian or 牛肉麵. It was the best soup I've ... http://www.mattmerry.com/blog/2008/07/19/white-boy-niu-ro-mian Well, we broke down the FBIN file into some sections and validated that the section identifiers were correct by locating the size following the section identifiers. I'm assuming at this point that the section sizes are part of section headers, and I don't know how long the headers are. Thats ... http://www.mattmerry.com/blog/2008/06/13/milestone-1-sd14-fpga-code  So a quick recap was dumping the largest CMbT section from the s14v101.bin file. I removed what I thought to be the header (everything before FBIN). I renamed this file s14v101.fbin. Now, I'll use the parsebin script to dump all the BINS sections. How do I know to do this? I ... http://www.mattmerry.com/blog/2008/06/12/fbin-file So, as I mentioned in the last post, there were some large sections in the bin files that require further investigation. The output of the parsebin script shows these sections. The most interesting to me is the large CMbT section. Lets look at s14v101.bin first. from parsebin: ***************************************************** CMbT: ***************************************************** Num Hex Length Dec Length Hex Position Dec ... http://www.mattmerry.com/blog/2008/06/12/cmbt So Sigma released an updated DP1 firmware today. Couple this with some interesting shots of the insides of the DP1 and turns out that there is a Xilinx chip and a custom ASIC (the Sigma TRUE) on the DP1. Way to go Sigma, custom ASICs, nice. According to the DP1 ... http://www.mattmerry.com/blog/2008/06/12/dp1-quick-look I love perl. Its great for parsing files, even binary files. The ParseBin.zip zip file contains a perl script I wrote (releasing under GPL 2.0). The script file basically attempts to parse the binary file, looking for sections. It will keep track of section location and size, print out information on ... http://www.mattmerry.com/blog/2008/06/08/perl-parser
