It will need *extensive* hacking to modify it to keep the +information about your custom boards that you want, however it is a good +starting point. + +How it is used: + + 1. a board has gone through all the hardware testing etc and is + ready to have the flash programmed for the first time - first you + go to a web page and fill in information about the board in a form + to register it in a database + + 2. the web stuff allocates a (unique) serial number and (optionally) + a (locally administered) ethernet address and stores the information + in a database using the serial number as the key (can do whole + batches of boards in one go and/or use a previously registered board + as defaults for the new board(s)) + + 3. it then creates a file in the tftp area of a server somewhere + containing the board information in a simple text format (one + per serial number) + + 4. all hymod boards have an i2c eeprom, and when U-Boot sees that + the eeprom is unitialised, it prompts for a serial number and + ethernet address (if not set), then transfers the file created + in step 3 from the server and initialises the eeprom from its + contents + +What this means is you can't boot the board until you have allocated a serial +number, but you don't have to type it all twice - you do it once on the web +and the board then finds the info it needs to initialise its eeprom. The +other side of the coin is the reading of the eeprom and how it gets passed +to Linux (or another O/S). + +To see how this is all done for the hymod boards look at the code in the +"board/hymod" directory and in the file "include/asm/hymod.h". Hymod boards +can have a mezzanine card which also have an eeprom that needs allocating, +the same process is used for these as well - just a different i2c address. + +Other forms provide the following functions: + + - browsing the board database + - editing board information (one at a time) + - maintaining/browsing a (simple) per board event log + +You will need: MySQL (I use version 3.23.7-alpha), PHP4 (with MySQL +support enabled) and a web server (I use Apache 1.3.x). + +I originally started by using phpMyBuilder (http://kyber.dk/phpMyBuilder) +but it soon got far more complicated than that could handle (but I left +the copyright messages in there anyway). Most of the code resides in the +common defs.php file, which shouldn't need much alteration - all the work +will be in shaping the front-end php files to your liking. + +Here's a quick summary of what needs doing to use it for your boards: + +1. get phpMyAdmin (http://phpwizard.net/projects/phpMyAdmin/) - it's an + invaluable tool for this sort of stuff (this step is optional of course) + +2. edit "bddb.css" to your taste, if you could be bothered - I have no + idea what is in there or what it does - I copied it from somewhere else + ("user.css" from the phpMyEdit (http://phpmyedit.sourcerforge.net) package, + I think) - I figure one day I'll see what sort of things I can change + in there. + +3. create a mysql database - call it whatever you like + +4. edit "create_tables.sql" and modify the "boards" table schema to + reflect the information you want to keep about your boards. It may or + may not be easier to do this and the next step in phpMyAdmin. Check out + the MySQL documentation at http://www.mysql.com/doc/ in particular the + column types at http://www.mysql.com/doc/C/o/Column_types.html - Note + there is only support for a few data types: + + int - presented as an html text input + char/text - presented as an html text input + date - presented as an html text input + enum - presented as an html radio input + + I also have what I call "enum_multi" which is a set of enums with the + same name, but suffixed with a number e.g. fred0, fred1, fred2. These + are presented as a number of html select's with a single label "fred" + this is useful for board characteristics that have multiple items of + the same type e.g. multiple banks of sdram. + +5. use the "create_tables.sql" file to create the "boards" table in the + database e.g. mysql dbname < create_tables.sql + +6. create a user and password for the web server to log into the MySQL + database with; give this user select, insert and update privileges + to the database created in 3 (and delete, if you want the "delete" + functions in the edit forms to work- I have this turned off). phpMyAdmin + helps in this step. + +7. edit "config.php" and set the variables: $mysql_user, $mysql_pw, $mysql_db, + $bddb_cfgdir and $bddb_label - keep the contents of this file secret - it + contains the web servers username and password (the three $mysql_* vars + are set from the previous step) + +8. edit "defs.php" and a. adjust the various enum value arrays and b. edit + the function "pg_foot()" to remove my email address :-) + +9. do major hacking on the following files: browse.php, doedit.php, donew.php, + edit.php and new.php to reflect your database schema - fortunately the + hacking is fairly straight-forward, but it is boring and time-consuming. + +These notes were written rather hastily - if you find any obvious problems +please let me know. |
