|
|
|
|
## Flashing
|
|
|
|
The MCB2388 is programmed via an ISP bootloader over UART. For this you have to
|
|
connect an USB-RS232 converter to the COM0 port.
|
|
|
|
Make sure to have the ISP Jumper set.
|
|
|
|
Connect the MCB2388 to your PC using the serial port and run from within the
|
|
folder of your application to flash:
|
|
|
|
BOARD=mcb2388 make flash
|
|
|
|
You'll notice that during the first invocation takes a bit longer, as the tool
|
|
`lpc2k_pgm` used to flash the MCB2388 is also compiled.
|
|
|
|
You can connect to the shell by running:
|
|
|
|
BOARD=mcb2388 make term
|
|
|
|
## Serial Terminal
|
|
|
|
By default the RST line is connected to the RTS/CTS line of COM0.
|
|
This will pull the MCU into reset when connecting a terminal. Use `pyterm -tg` to
|
|
toggle the pins and complete the reset.
|
|
|
|
If you want to connect a terminal application that does not support this, remove
|
|
the RST jumper from the board.
|
|
You will not be able to flash the board using `lpc2k_pgm` if the RST jumper is
|
|
disconnected.
|
|
|
|
## Debugging
|
|
|
|
The development kit comes with a ULINK-ME Debug Unit that supports the CMSIS-DAP
|
|
protocol.
|
|
Connect it with the JTAG port on the board, the debugging should work by typing
|
|
|
|
BOARD=mcb2388 make debug
|
|
|
|
### Flashing via OpenOCD
|
|
|
|
Theoretically you should be able to flash also via JTAG.
|
|
Unfortunately OpenOCD support for this chip family seems to be pretty buggy.
|
|
I was unable to flash the board using the ULINK-ME adapter and OpenOCD. (2019)
|
|
|
|
The board might get stuck when using OpenOCD, you have to power-cycle it to
|
|
being able to use ISP programming again.
