Hi!
I'm testing an embedded system with gdb using remote target.
Examining memor works fine as described at
http://sources.redhat.com/gdb/onlinedocs/gdb_9.html#SEC59
But I couldn't find any easy command with I could modify the content of
a given memory address, only if I create a one-byte-long file containing
my data.
For example:
--------------------------------------------------------
(gdb) x/b 0x800000C0
0x800000c0: 0x00
(gdb) restore one.dat binary 0x800000C0
Restore file one.dat offset 0x800000c0 start 0x0 end 0x0
Restoring binary file one.dat into memory (0x800000c0 to 0x800000c1)
(gdb) x/b 0x800000C0
0x800000c0: 0x01
(gdb) restore zero.dat binary 0x800000C0
Restore file zero.dat offset 0x800000c0 start 0x0 end 0x0
Restoring binary file zero.dat into memory (0x800000c0 to 0x800000c1)
(gdb) x/b 0x800000C0
0x800000c0: 0x00
(gdb)
--------------------------------------------------------
Do I need to create a file when I want to write a byte of data?
Thanks.
