The RBTX4927 (RBHMA4200) and RBTX4937 (RBHMA4400) boards are based off the TMPR4927 and TMPR4937 processors respectively. These boards have 32-bit PCI slot, Fast Ethernet interface, Two Serial ports (16550 compatible) and 128 MB memory. They can operate in either BE or LE mode.
Currently, RBTX4927 is supported in Linux 2.4 and 2.6 as well, RBTX4937 is supported only in 2.6.
Prepare an srec image of the kernel. On the PMON prompt of the board, type load. For example:
Downloading from ethernet, ^C to abort Entry address is 80297018
At this point, from the host, do the following using tftp:
# tftp 10.0.12.182 tftp> bi tftp> put vmlinux.srec Sent 8052180 bytes in 183.1 seconds
And at this point, you should see something similar to the following on the target:
total = 0x28f461 bytes PMON>
At this point, type "g" and you should be able to get the kernel up and running.
