Software architecture 45/70
2.4.2 Console mode
The purpose of the console mode is to enable the handling of firmware
programming and chip-level security settings.
The console mode is entered on the following conditions:
·
After a software reset cycle if the firmware has initiated the console
mode beforehand
· After a hardware reset if the RDY pin has been connected to GND
beforehand (see figure
Pin configuration for operating
modes [
}
page 44])
· After a hardware reset if neither (valid) communication firmware nor
maintenance firmware can be found
The console mode allows access to the netX 90 via UART, Ethernet or host
interface.
This “console mode interface” is determined by the configuration settings of
the
SQI_SIO0
,
SQI_SIO1
and
SQI_SIO2
pins as shown in the table
below:

Table 24: Configuration of console mode interfaces
The UART console mode allows firmware programming via serial/UART
interface. The console modes for host interface enable firmware
programming through the application host if the device is used as a
companion chip. The console mode for the Ethernet interface enables
firmware programming by using utility tools or via DHCP/TFTP server. In
addition, the ROM code provides an Ethernet switch and a web server for
software updates.
