The LXT97x is an ethernet PHY (which is just the physical layer used by some ethernet chips). Normally, there is little (or nothing) required to control these devices - they just do their job. They do have a control interface whereby you can set the hardware bit rate, e.g. 100Mb or 10Mb, detect the presence of a carrier/cable, etc. They are not [directly] responsible for passing ethernet data, that job is handled by some other device. You need to figure out what the actual ethernet device is; depending on the platform, this may be a separate device like an 82559 chip, etc, or it may be builtin to the CPU (SOC), e.g. on the XScale devices. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss ^ permalink raw reply [flat|nested] 6+ messages in thread

It is actually a ship set from Intel LXT971ABE A4 L549ID42. The Ethernet of our board worked when the RTL820 was used, but now the redboot cannot connect to the network since replacing to Intel LXT971. Sorry, I am new to the redboot. I thought to get some advices from experts on this list before plunging into the debug. Any more information and helps would be great appreciated. Thank you.

Long file names require quite a lot of changes to the filesystem. We (eCosCentric) have added LFN support to our version of the FATFS. This is currently available through our eCosPro product. There are also patent issues with Microsoft, which means that many commercial users are reluctant to use LFN at present. -- Nick Garnett eCos Kernel Architect http://www.ecoscentric.com The eCos and RedBoot experts -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss ^ permalink raw reply [flat|nested] 6+ messages in thread
