Serial Console
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
By default, the serial console will be provided on the OpenSDA VCOM port:
|
|
|
|
|
|
|
|
|
|
OpenSDA UART TX PTC7 (LPUART1_TX)
|
|
|
|
|
OpenSDA UART RX PTC6 (LPUART1_RX)
|
|
|
|
|
|
2021-09-14 17:45:06 +02:00
|
|
|
USB drivers for the PEmicro CDC Serial Port are available here:

LEDs
|
|
|

|
|
|
|
|
The S32K148EVB has one RGB LED:
|
|
|
|
|
|
2021-09-14 17:45:06 +02:00
|
|
|
RedLED PTE21 (FTM4 CH1)
|
|
|
|
|
GreenLED PTE22 (FTM4 CH2)
|
|
|
|
|
BlueLED PTE23 (FTM4 CH3)
|
2019-08-21 01:02:29 +02:00
|
|
|
|
2019-08-22 20:12:22 +02:00
|
|
|
An output of '1' illuminates the LED.
|
|
|
|
|
|
2019-08-21 01:02:29 +02:00
|
|
|
If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs in
|
|
|
|
|
any way. The following definitions are used to access individual RGB
|
2021-09-14 17:45:06 +02:00
|
|
|
components (see s32k148evb.h):
|
|
|
|
|
|
|
|
|
|
GPIO_LED_R
|
|
|
|
|
GPIO_LED_G
|
|
|
|
|
GPIO_LED_B
|

|
|
|
|
2021-09-14 17:45:06 +02:00
|
|
|
The RGB components could, alternatively, be controlled through PWM using
|
2019-08-21 01:02:29 +02:00
|
|
|
the common RGB LED driver.
|
|
|
|
|
|
|
|
|
|
If CONFIG_ARCH_LEDs is defined, then NuttX will control the LEDs on board
|
2020-02-07 13:53:40 +01:00
|
|
|
the S32K148EVB. The following definitions describe how NuttX controls the

- Using Segger J-Link: Easy... but remember to use the 20-pin SWD
|
|
|
|
|
connector J10 near the ethernet connector and not the 10-pin OpenSDA
|
|
|
|
|
connector J20 closer to the OpenSDA USB connector J24.

|
|
|
Each S32K148EVB configuration is maintained in a sub-directory and can be
|
|
|
|
|
selected as follows:
|
2019-08-21 01:02:29 +02:00
|
|
|
|
|
|
|
|
tools/configure.sh s32k148evb:<subdir>

|
|
|

2021-09-14 17:45:06 +02:00
|
|
|
1. This configuration uses the mconf-based configuration tool. To change
|
|
|
|
|
this configuration using that tool, you should:
|
2019-08-21 01:02:29 +02:00
|
|
|
|
2021-09-14 17:45:06 +02:00
|
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt.
|
|
|
|
|
Also see additional README.txt files in the NuttX tools repository.
|
2019-08-21 01:02:29 +02:00
|
|
|
|
|
|
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
|
|
|
|
reconfiguration process.
|
|
|
|
|
|
|
|
|
|
2. Unless otherwise stated, the serial console used is LPUART1 at
|
|
|
|
|
115,200 8N1. This corresponds to the OpenSDA VCOM port.
