- Subject: GDB using Angel error on an OKI board
Hello,
I'm using an OKI developpement board with the OKI ML671000 processor, this
is provide with an
ARM SDT 2.50 software and an ARM Angel 1.20 in the flash memory on the
board, when I use
the ARM Debugger with an angel link, all work fine in 9600 or 19200, the
message in the console
box at the start is the next :
Angel Debug Monitor V1.20 (ARM Ltd unreleased) for ML671000 CPU Board(OKI)
Built for ARM7TDMI Serial(x1), IRQ
Unreleased build Mar 14 2000
Serial Rate: 9600
all operation with memory, registers ... work fine with this debugger.
My problem is with arm-elf-gdb 5.1.1, when I start the software, the board
don't response any time
the next lines show how I start the link with the Angel on the OKI board :
$ arm-elf-gdb
