End-of-line programming 48/70
3.1.2 Using console mode and serial/UART interface
If the netX is in console mode, the ROM code supports firmware
programming via the UART pins of the COM CPU peripherals (i.e. if the
pins are accessible. Consult the hardware documentation of your netX 90
device for information on whether it is equipped with a serial/UART
interface).
Note:
The current version of the Flasher tool does not yet support flashing
via serial/UART interface.
Requirements
· Your netX 90 device is equipped with a UART interface (either “on-
board” or external):
– UART-to-USB adapter (FTDI bridge)
or
– UART-to-RS232 adapter (featuring an RS232 transceiver)
·
The UART interface adapter is connected to your programming PC/
laptop via
– USB (in case of FTDI bridge)
or
– D-Sub connector/COM port (in case of RS232 adapter)
·
Programming tool on PC/laptop:
– netX Studio CDT (integrated Flasher tool)
or
– Command line flasher
Entering console mode
In its initial “blank” state, the netX 90 automatically supports firmware
programming in console mode via UART; i.e. you do not need make any
configuration settings in order to enable this option.
This is because the netX automatically enters console mode if the ROM
code cannot find a valid firmware after a power cycle (see section
Boot
process [
}
page 42]) and because UART is always the default console
mode interface, regardless of the configuration settings of the SQI_SIO
pins (see also section
Console mode [
}
page 45]).
Note:
If the netX 90 is not in its “blank” state because a valid
communication firmware is already residing in the flash, you can
“force” the ROM code into console mode by pulling the RDY pin of
the netX 90 to GND (i.e. if the pin is accessible. Consult the
hardware documentation of your netX 90 device for information on
this).
