Hi all, I've had a quick look around both on the web, and in amongst the RedBoot sources I have here (which were supplied by Ka-Ro) but haven't found an answer yet... my appologies if this has been answered before.
We're using Ka-Ro's TX27 modules in a product being developed... these modules have almost a complete embedded Linux computer on a little SO-DIMM card which can be removed and swapped between baseboards. The baseboards have a small 16kB I²C EEPROM (a 24c16-class device) in which we'd like to store things like the board's serial number, and most importantly, the board's type. This can then be made available to the Linux kernel either via the bootloader tags, or via the kernel command line. That way, regardless of the board the TX27 module is plugged into, assuming the EEPROM is pre-programmed with the right data, it can determine what it's running on, and will work. (e.g. field replacements, etc...) I'm aware that RedBoot (or rather eCos) has a HAL which implements access to the I²C bus. There are also some flash chips supported, but what's not clear is whether there's a 24c16 device driver in there, or anything similar. Is there an implementation of an I²C EEPROM in RedBoot already?
