RE: eCos Port for TI TMS320DM270 (ARM7) Processor


Hi Mr. Chee Tim. Hi, everyone.

I also work on TMS320DSC25/TMS320DM270 and somewhat similar, somewhat
different archievement in eCos porting.

Because this work is concerning about my company job, and my company made
NDA with TI, I'm not sure that I can send my patch to eCos community.
Could anyone advice me about some legal issue ?

Subject: eCos Port for TI TMS320DM270 (ARM7) Processor

The attached patch, against eCos 2.0, adds support for TI TMS320DM270
processor on the XEVM-DM270GHK Version 2.0 evaluation board. Communication
and downloads are supported by both built-in serial ports and on-board
Cirrus Logic CS8900A ethernet chip. The default serial port settings are
38400,8,N,1. Flash management is supported for the on-board Toshiba
TC58FVT160AFT 2MB flash.

Also included are minor updates to
1. RedBoot to support booting uClinux on ARM 2. cs8900a ethernet driver to
additionally check that checksum of the EEPROM readout is correct before
reading MAC address from it 3. am29xxxxx flash driver to handle flash that
is not at address 0 4. stand-alone ethernet driver in io package to
additionally check that ethernet packet length is greater than length of
ethernet header (14) to avoid memcpy of large number of bytes as a result of
a negative number

Please feel free to comment on the patch and its suitability for inclusion
into cvs.
