102. vmemb - syntax
NAME
vmemb - AMBA bus 8-bit virtual memory read access, list a range of addresses
SYNOPSIS
vmemb ?-ascii? address ?length?
DESCRIPTION
vmemb ?-ascii? address ?length?
GRMON will translate address to a physical address, do an AMBA bus read 8-bit read access and print
the data. The optional length parameter should specified in bytes and the default size is 64 bytes. If no
MMU exists or if it is turned off, this command will behave like the command vwmemb
NOTE: Only JTAG debug links supports byte accesses. Other debug links will do a 32-bit read and then
parse out the unaligned data.
OPTIONS
-ascii
If the -ascii flag has been given, then a single ASCII string is returned instead of a list of values.
-cstr
If the -cstr flag has been given, then a single ASCII string, up to the first null character, is returned
instead of a list of values.
RETURN VALUE
Upon successful completion vmemb returns a list of the requested 8-bit words. Some options changes the result
value, see options for more information.
EXAMPLE
Read 4 bytes from address 0x40000000:
grmon3> vmemb 0x40000000 4
TCL returns:
64 0 0 0
