## Summary A lot of linker scripts were listed twice, once for unix, once for windows. This PR cleans up the logic so they're only listed once. ## Impact Any opportunity to use a single source of truth and reduce lines of code is a win! ## Testing CI will test all build |

README ====== This directory holds the port to the NXP S32K118EVB-Q064 development board. Contents ======== o Status o Serial Console o LEDs and Buttons o OpenSDA Notes o Configurations Status ====== 2019-08-14: Configuration created but entirely untested. 2019-08-17: The port is code complete. It compiles with no errors or warnings but is untested. Still waiting for hardware. 2019-08-20: The very first image that I wrote to FLASH seems to have "bricked" the board. The board is sensitive to (1) resetting into a bad state and (2) incorrect flash configurations. It is difficult to impossible to recover from these start-up errors. 2019-08-22: My S32K118EVB is still borked, but after some additional changes, Fabio Balzano has verified that the NSH is functional on that board. 2019-10-19: The aforementioned fixes for the FLASH issues were converted into a set of FLASH configuration options, with a proven default state. 2020-06-15: Added FlexCAN driver with SocketCAN support to the S32K1XX arch. Might work on the S32K118EVB as well, but remains untested. 2020-06-16: Added Emulated EEPROM driver and initialization. TODO: Need to calibrate the delay loop. The current value of CONFIG_BOARD_LOOPSPERMSEC is a bogus value retained from a copy-paste (see apps/examples/calib_udelay). Serial Console ============== By default, the serial console will be provided on the OpenSDA VCOM port: OpenSDA UART RX PTB0 (LPUART0_RX) OpenSDA UART TX PTB1 (LPUART0_TX) USB drivers for the PEmicro CDC Serial Port are available here: http://www.pemicro.com/opensda/ LEDs and Buttons ================ LEDs ---- The S32K118EVB has one RGB LED: RedLED PTD16 (FTM0 CH1) GreenLED PTD15 (FTM0 CH0) BlueLED PTE8 (FTM0 CH6) An output of '1' illuminates the LED. 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 components (see s32k118evb.h): GPIO_LED_R GPIO_LED_G GPIO_LED_B The RGB components could, alternatively, be controlled through PWM using the common RGB LED driver. If CONFIG_ARCH_LEDs is defined, then NuttX will control the LEDs on board the S32K118EVB. The following definitions describe how NuttX controls the LEDs: ==========================================+========+========+========= RED GREEN BLUE ==========================================+========+========+========= LED_STARTED NuttX has been started OFF OFF OFF LED_HEAPALLOCATE Heap has been allocated OFF OFF ON LED_IRQSENABLED Interrupts enabled OFF OFF ON LED_STACKCREATED Idle stack created OFF ON OFF LED_INIRQ In an interrupt (no change) LED_SIGNAL In a signal handler (no change) LED_ASSERTION An assertion failed (no change) LED_PANIC The system has crashed FLASH OFF OFF LED_IDLE S32K118 in sleep mode (no change) ==========================================+========+========+========= Buttons ------- The S32K118EVB supports two buttons: SW2 PTD3 SW3 PTD5 OpenSDA Notes ============= - USB drivers for the PEmicro CDC Serial Port are available here: http://www.pemicro.com/opensda/ - The drag'n'drog interface expects files in .srec format. - Using Segger J-Link: Easy... but remember to use the SWD connector J14 near the touch electrodes and not the OpenSDA connector near the OpenSDA USB connector J7. Configurations ============== Common Information ------------------ Each S32K118EVB configuration is maintained in a sub-directory and can be selected as follows: tools/configure.sh s32k118evb:<subdir> Where <subdir> is one of the sub-directories listed in the next paragraph. NOTES (common for all configurations): 1. This configuration uses the mconf-based configuration tool. To change this configuration using that tool, you should: a. Build and install the kconfig-mconf tool. See nuttx/README.txt. Also see additional README.txt files in the NuttX tools repository. b. Execute 'make menuconfig' in nuttx/ in order to start the reconfiguration process. 2. Unless otherwise stated, the serial console used is LPUART0 at 115,200 8N1. This corresponds to the OpenSDA VCOM port. Configuration Sub-directories ----------------------------- nsh: --- Configures the NuttShell (nsh) located at apps/examples/nsh. Support for builtin applications is enabled, but in the base configuration no builtin applications are selected. NOTE: This is a very minimal NSH configuration in order to reduce memory usage. Most of the NSH niceties are not available.
