Details

mread reads 32-bit values from the memory of a Fusiv AP. It is part of the sysutil multi-call binary.
To write to the AP memory use mwrite.

In the Fusiv an AP is a 400 MHz Xtensa Acceleration Processor. On a 7390 there are 6 of them:

There is also some info about the APs in the old wiki (german).

Wrong Number Of Parameters

[mread/mwrite] <mem-address> <len> <value>

    mread/mwrite : Memory read or write operation
    mem-address  : 32bit Address in hex range 0x80000000 - 0xc0000000 
    len          : No.of 32bit words in Decimal to read/write 
    value        : 32bit Value to be written at 
                   mem-address location

    Ex: mread b9110300 10 
        mwrite 801ecfb4 1 11112222

7390 fw 6.04 examples:

root@fritz:/var/mod/root# mread b9110300 10 

0xb9110300: 00007c1e  00007c1e  00007c1e  00007c1e

Excerpt of a strace of this example:

root@fritz:/var/mod/root# strace mread b9110300 10 2>&1 | grep -e proc -e write

open("/proc/sysutil/utilfile", O_RDWR)  = 3
write(3, "2 0b9110300 010", 15)         = 15
write(1, "\n 0xb9110300: 00007c1c  00007c1c"..., 144
