Hi All
Due to some interest in running the uTasker on the M5282 some work has been started to prepare this.
First of all - this is quite an old Coldfire device, available in 256 MAPBGA (making it quite expensive too). At the moment there are some patent problems due to the housing which restricts the device in the USA (should be lifted October 2010).
Belonging to this family there are the following devices:
• M5214 – 64k SRAM and 256k FLASH; CAN but no Ethernet
• M5216 – 64k SRAM and 512k FLASH; CAN but no Ethernet
• M5280 – 64k SRAM but no FLASH
• M5281 – 64k SRAM and 256k FLASH
• M5282 – 64k SRAM and 512k FLASH
They all have a 32 bit wide external memory interface allowing SDRAM, which is their biggest attraction or a high port count when not used, or only partially used.
The development is being documented (in form of a developer's guide specifically to explain its main differences to the M522XX devices). This can be found and monitored here:
http://www.utasker.com/docs/documentation.html#M5282At the moment the development is being performed exclusively in the uTasker simulator (with some useful code references from a uTasker project already running on it -
thanks Andrija) while a development board is organised.
Comments are welcome, as are developers who would like to test the new support on their existing HW.
Regards
Mark
