Re: [ECOS] How to test the serial connection with HyperTerminal in NECVRC4373

["Ling Su" <lingsu at palmmicro dot com>]

Thanks, after I contact with NEC technical support, the board has been boot
up.

I will trying to build eCos for this target, one thing I met is the NEC
board comes together with the GNUPro toolchain for VR4373 board, the version
is NEC-990510, and all the command has a prefix like mips64vr4xxxel-elf, so
if I start to build, it will complain that it can not find
mips64vr4300-elf...., then I go to the Tools->Platforms and change the
prefix for vrc4373 platform. Then the eCos configure tool will crashed
during build. I do not understand why? I have report the bug in eCos bug
list, is there any fix?

Really, I need to burn another ROM to enable the debugging funciton? I find
in the manual "GNUPro Toolkit User's Guide for NEC VR4xxx", it doesn't
mention any new boot ROM and use mips64vr4xxxel-elf-gdb to debug... anyway,
I will try it.
