Serial Console
==============
To be provided
By default UART1 is used as the serial console on these boards. NUC120LE3AN
is provided as an LQFP48 package and, for this case, the UART1 RX signal
(RXD1) is on PB.4, pin 8, and the TX signal (TXD1) is on PB.5, pin 9.
These pins are available on the NuTiny-SDC-NUC120 JP5.
NOTE: The TX vs RX terminology is confusing. On my RS-232 driver board,
I need to connect the NUC120 TXD0 pin to the driver boards RXD pin. How
confusing!
UART0 is an alternative that can be selected by modifying the default
configuation. UART0 RX (RXD0) is on PB.0, pin 17, and the TX signal (TXD0)
is on PB.1, pin 18. These pins are available on the NuTiny-SDC-NUC120 JP1.
NOTE: PB.0, pin 17, is also used to control the user LED on board (labeled
"IO"). CONFIG_ARCH_LED should not be selected if UART0 is used.
The NUC120LE3AN does not support UART2.
Debugging
=========
The NuTiny-SDK-NUC120 includes a built-in NuLink debugger. Unfortunately,
full debug support is available only with the Keil and IAR toolchains.
There is, however, a free program call call ICP (In-Circuit Programmer).
It can be used to burn programs into FLASH (aka APROM).
There is, however, a free program called ICP (In-Circuit Programmer). It
can be used to burn programs into FLASH (aka APROM).
The ICP program can also be used to burn an ISP program into LDROM. The
ISP (In-System Programmer) is available free from the Nuvton website.
Then NuttX build does not set the configuration words at 0x0030000-0x00300004.
You should uncheck the Config box when burning APROM or the previous contents
of the configuration words will be erased.
