Details
mwrite writes 32-bit values to the memory of a Fusiv AP. It is part of the sysutil multi-call binary.
To read from the AP memory use mread.
In the Fusiv an AP is a 400 MHz Xtensa Acceleration Processor. On a 7390 there are 6 of them:
- 1 - Eth0 - Ethernet - ethdriver_lkm.ko
- 2 -
Eth1 - 3 -
Eth2 / xDSL - 4 - SEC - VPN / Security - aclap_driver_lkm.ko
- 5 - BM - Buffer Manager - bmdriver_lkm.ko
- 6 -
ADSL / ATM- atmdriver_lkm.ko - 7 - HAP - Hardware / Peripherals - periap_driver_lkm.ko
- 8 -
VDSL- vdsldriver_lkm.ko - 9 - CLAP1 - Classifier - classifier_driver_lkm.ko
- 10 - CLAP2 - Classifier - classifier_driver_lkm.ko
There is also some info about the APs in the old wiki (german).
