msp430-jtag and the msp430-gdbproxy.
msp430-jtag can use two backends
1) MSP430.dll/so
2) MSP430mspgcc.dll/so
1: the library you get for your USB programmer or with the FET kits
from TI. parallel and JTAG adapters. This is the same library that is
used by msp430-gdbproxy
2: the open source implementation based on slaa149. it only supports
parallel port adapters.
there are some small differences between the backens, see msp430-jtags
--help nad --help-backends
USB adapters are typically faster than the parallel port adapters.
differences between gdbproxy and the other tool is how the library is
used. for gdbproxy you need to set the block size to get fast downloads.
and it may try to start/stop the CPU and upload RAM/registers as it is
a debugger. but in raw download speed, should both get about the same.
in the past, there were cases where msp430-gdbproxy downloaded much
slower than theoretically possible. one reason was the block size, but i
don't know if there were also other issues and if all of them were solved.
so if one of this files is "better" which one is the right choice?
if it is for production use, you may also consider a commercial
programmer. there are some that are even faster, and i don't give you
any guarantees that the flash is optimally programmed for long term
memory retention using the open source backend.
