RedBoot 'load' command does stat info about 'Entry point'. For example
on my ARM target
RedBoot> load -m y
Entry point: 0x81008040, address range: 0x81008000-0x81013890
xyzModem - CRC mode, 627(SOH)/0(STX)/0(CAN) packets, 2 retries

Load address 0x81008000 and entry point (LMA of .text) is 0x81008040.
If I load a binary, I got something likes this
RedBoot> load -m y -r -b 0x81008000
CRaw file loaded 0x81008000-0x8101388f, assumed entry at 0x81008000
xyzModem - CRC mode, 372(SOH)/0(STX)/0(CAN) packets, 3 retries

RedBoot has no clue where start from (it can guess only, 'assumed
entry')
From your old message
http://ecos.sourceware.org/ml/ecos-discuss/2014-10/msg00007.html
I see that after loading PC register will be set to 0x64008110, so try
RedBoot> go 0x64008110
> I get rubbish ($T080f:00800064;0d:e8cf1b64;)
Connect GDB to get it.

See/try above.

It should work.
