NAME
vwmems - Write a string to an AMBA bus virtual memory address
SYNOPSIS
vwmems
address
data
DESCRIPTION
vwmems
address
data
Do an AMBA write access. GRMON will translate
address
to a physical address and write the string
value specified by
data
, including the terminating NULL-character. If no MMU exists or if it is turned
off, this command will behave like the command vwmems'
NOTE: Only JTAG debug links supports byte accesses. Other debug links will do a 32-bit read-modi-
fy-write when writing unaligned data.
RETURN VALUE
vwmems has no return value.
EXAMPLE
Write "Hello World" to address 0x40000000-0x4000000C:
grmon3> vwmems 0x40000000 "Hello World"
