From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Anthony Massa" To: "Gary Thomas" Cc: "eCos" Subject: RE: [ECOS] RedBoot Date: Wed, 27 Dec 2000 16:49:00 -0000 Message-id: <00c901c07067$6c603280$0200a8c0@cts.com> References: X-SW-Source: 2000-12/msg00417.html I was able to change the MAC address (using fconfig). I am able to do ping from Win NT host and get back packets. I cannot run using BOOTP, I must use a static IP address. However, I still am not able to run the telnet application and connect to the MBX board. Do you know what is the problem there? Do I need to run a BOOTP server from my host? Should I try a tftp server application? > > As I expected, the problem is that RedBoot/eCos can't get at the NVRAM > information.
