ST STR912FW44 support

Posted by baxsie on May 29, 2006
I am looking at the STR912FW44:

http://mcu.st.com/mcu/modules.php?name=mcu&file=devicedocs&DEV=STR912FW44&FAM=101

It is a pretty nice part:

96 MHz ARM 9
CAN
USB
Ethernet
512KB flash
96KB RAM

All integrated on a single chip. Pricing looks reasonable with DigiKey showing about $17 and my disty promising < $10 in quantity.

I have been looking at the Atmel AT91SAM7X, but since the project got delayed and the STR912FW44 is now available, I am considering using it.

Are there plans to port FreeRTOS to the STR912FW44 ?

I may be able to arrange a development system if you need one.

HAL code for the STR912FW44

Interesting:

Firmware library
ST freely distributes Hardware Abstraction Layer (HAL) library
source files for the STR910F from www.st.com/mcu. This tested
and proven collection of standard ANSI ā€˜Cā€™ functions manipulates
all low level silicon functions, freeing you from worrying about
the details so you can immediately start developing your
application. Just include the functions in your project and call
them from your own drivers, RTOS, communication stack, or
application code.

The code is linked from this page:
http://mcu.st.com/mcu/modules.php?name=mcu&file=devicedocs&DEV=STR912FW44&FAM=101
in the "software" table.

The odd think is that I do not see an evaluation board from ST for this processor.

I am getting more enquiries about ARM9 than anything else at the moment. A FreeRTOS.org port is needed! I think the main areas of difference are going to be how to handle the MMU and Cache.

Regards.

I have not read it in detail yet, but looks interesting indeed.

Regards.
