The board is a very simple -- little more than a carrier for the PIC32 MCU plus voltage regulation, debug interface, and an OTG connector.

The port for this board was completed in NuttX 6.11, but still required a few bug fixes before it will be ready for prime time.
|
|
|
|
|
The fully verified port first appeared in NuttX 6.13.

From what I can tell using MPLAB, the NuttX port is running and fully functional on the Starter Kit.
|
|
|
|

The only configuration available as of this writing is the OS test which depends on serial output for full verification.

|
|
|
|
* arch/arm/src/stm32/stm32f40xxx_dma.c: Add DMA support for the STM32 F4
|
|
|
|
|
family (untested on initial check-in)
|
|
|
|
|
* arch/arm/src/armv7-m/up_fpu.c: Add logic for saving an restoring VFP
|
|
|
|
|
floating point registers on context switches (but also disable the FPU
|
|
|
|
|
because CodeSourcery doesn't support hard flowing point!)
|
|
|
|
|
* arch/arm/src/stm32/chip/stm32_eth.h: Add Ethernet register definitions
|
|
|
|
|
for the STM32 F4.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32_eth.c: Adds an Ethernet driver for the STM32 F4.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32_dac.c and stm32_adc.c: "Skeleton" files for STM32
|
|
|
|
|
DAC and ADC drivers. The actual logic will come later.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32_eth.c: There may be a few more lurking bugs, but
|
|
|
|
|
the STM32 Ethernet driver appears to be fully functional on the STM3240G-EVAL.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32_eth.c: Fix an error in clearing abnormal interrupt
|
|
|
|
|
events.
|
|
|
|
|
* configs/stm3240g-eval/dhcpd: Add a DCHP daemon configuration for the
|
|
|
|
|
STM3240G-EVAL board.
|
|
|
|
|
* configs/stm3240g-eval/nettest: Add a network test configuration for the
|
|
|
|
|
STM3240G-EVAL board.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32_rtc.c, stm32f10xxx_rtc.c, and stm32f40xxx_rtc:
|
|
|
|
|
Broke out separate drivers to handle the very different RTC implementations
|
|
|
|
|
in the STM32 F1 and F4 family.
|
|
|
|
|
* arch/arm/srcm/stm32/stm32f10xxx_rtc.c: STM32 F4 RTC is functional (12/14/2011)
|
|
|
|
|
* net/uip-arp.c: Fix compilation issue with CONFIG_NET_ARP_IPIN
|
|
|
|
|
* include/nuttx/pwm.h and drivers/pwm.c: Add an interface definition and a
|
|
|
|
|
"upper half" driver for PWM output.
|
|
|
|
|
* arch/arm/src/stm32/stm32_pwm.c: Added a PWM "lower half" driver for the
|
|
|
|
|
STM32. The initial check-in is little more than a framework for the driver.
|
|
|
|
|
* arch/arm/src/stm32/stm32_usbdev.c: Corrected two CRITICAL errors in the USB
|
|
|
|
|
device-side driver: (1) Handling of data overrun condition was wrong. When
|
|
|
|
|
there was no further memory to accept further OUT endpoint data, the driver
|
|
|
|
|
would hang with infinite interrupts; (2) the logic in setting toggle bits
|
|
|
|
|
was not correct. However, this driver has functioned for a long time until
|
|
|
|
|
the particular condition that revealed the bug occurred. My impression is
|
|
|
|
|
that this latter bugfix also fixes some STM32 USB performance problems.
|
|
|
|
|
* configs/hymini-stm32v: A configuration for the HY-Mini STM32v board contributed
|
|
|
|
|
by Laurent Latil. Theses changes also include support for the STM32F103VCT6.

|
|
|
|
|
apps/examples/pwm test of the STM32 PWM driver.
|
|
|
|
|
* drivers/mtd/mp25x.c: Add ability to use different SPI modes and different
|
|
|
|
|
manufacturers codes. Fix a error in the wait for not busy (submitted by
|
|
|
|
|
Mohammad Elwakeel.
|
|
|
|
|
* arch/arm/src/stm32/stm32_can.c. Add a low-level STM32 CAN driver. (Initial
|
|
|
|
|
check is incomplete). Add loopback support to the driver.
|
|
|
|
|
* arch/arm/src/stm32/stm32_adc.c. The ADC is now functional. A more complete
|
|
|
|
|
driver would require DMA support. I have some questions still about the
|
|
|
|
|
accuracy of the timer-driven sampling.
|
|
|
|
|
* configs/sure-pic32mx/nsh. The PIC32 port is (finally) functional. Add an
|
|
|
|
|
NSH configuration for the Sure PIC32MX board.
|
|
|
|
|
* configs/sure-pic32mx/*/defconfig. Calibrated all PIC32 delay loops.
|
|
|
|
|
* configs/pcblogic-pic32mx/nsh. Add an NSH configuration for the PCBLogic
|
|
|
|
|
PIC32 board.
|
|
|
|
|
* Both PIC32 OS test and NSH configurations have now been verified.
|
|
|
|
|
* tools/Makefile.export, mkexport.sh, and configure.sh: Changes submitted
|
|
|
|
|
by Mike Smith to support configuration and 'make export' on MAC OS.
|
|
|
|
|
* arch/arm/src/stm32/stm32_gpio.c: Disabled interrupts while configuring
|
|
|
|
|
GPIO pins so that we have exclusive access to the GPIO configuration
|
|
|
|
|
registers.
|
|
|
|
|
* arch/mips/src/pic32mx/pic32mx_usbdev.c: Add a USB device-side driver
|
|
|
|
|
for the PIC32MX family.
|
|
|
|
|
* arch/arm/src/stm32/stm32_gpio.c: Correct an error in some of the GPIO
|
|
|
|
|
initialization logic. Fix submitted by Mike Smith.
|
|
|
|
|
* configs/olimex-lpc1766stk/src/up_leds.c: Add new interfaces so that is
|
|
|
|
|
CONFIG_ARCH_LEDS are not set, the LEDs may be controlled from application
|
|
|
|
|
logic.
|
|
|
|
|
* configs/olimex-lpc1766stk/src/up_buttons.c: Add support for the buttons
|
|
|
|
|
on the Olimex LPC1766-STK board.
|
|
|
|
|
* Makefile: Added 'apps_clean' and 'apps_distclean' target to simplify
|
|
|
|
|
managing the state of the application directory while in the NuttX directory
|
|
|
|
|
* Documentation/NuttXGettingStarted.html: Added a "Getting Started" Guide
|
|
|
|
|
for NuttX. At present, this is just a stub and it refers to the NuttX
|
|
|
|
|
top-level README.txt file which is the only, real "Getting Started" Guide
|
|
|
|
|
that exists at the time being.
|
|
|
|
|
* arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct an value used as the lower
|
|
|
|
|
end of an IRQ number range test.
|
|
|
|
|
* arch/arm/src/lpc17xx/lpc17_gpio.c: Fix a integer flow problem in shift.
|
|
|
|
|
This error would prevent pins > 15 from being used as interrupt sources.
|
|
|
|
|
* arch/arm/src/stm32/stm32_can.c: The CAN driver has been verified in
|
|
|
|
|
loopback mode on the STM3240G-EVAL board.
|
|
|
|
|
* configs/stm3240g-eval/src/up_adc.c: Complete coding of ADC support for the
|
|
|
|
|
potentiometer on board the STM3240G-EVAL.
|
|
|
|
|
* arch/arm/src/lpc17_can.c: Several CAN driver improvements. Adds support for
|
|
|
|
|
testing in loopback mode. now uses all three transmit buffers for better
|
|
|
|
|
performance.
|
|
|
|
|
* confgs/olimex-lpc1766stk/nsh: Now supports the CAN loopback test as an
|
|
|
|
|
optional "built-in" application.
|
|
|
|
|
* sched/irq_attach.c: Fix an issue with disabling interrupts when they are
|
|
|
|
|
detached. For the PIC32, this can't be done because there is a 1-to-many
|
|
|
|
|
relationship between vector numbers and interrupt numbers or different.
|
|
|
|
|
Added a new configuration option CONFIG_ARCH_VECNOTIRQ to at least flag
|
|
|
|
|
the architectures that have this issue and to (at least) avoid doing
|
|
|
|
|
something too wrong.
|
|
|
|
|
* drivers/can.c: Fix a test for buffer full in the generic, "upper half",
|
|
|
|
|
can driver.

|
|
* tools/Makefile.export, mkexport.sh, and configure.sh: Changes submitted
|
|
|
|
|
by Mike Smith to support configuration and 'make export' on MAC OS.
|
|
|
|
|
* arch/arm/src/stm32/stm32_gpio.c: Disabled interrupts while configuring
|
|
|
|
|
GPIO pins so that we have exclusive access to the GPIO configuration
|
|
|
|
|
registers.
|
|
|
|
|
* arch/mips/src/pic32mx/pic32mx_usbdev.c: Add a USB device-side driver
|
|
|
|
|
for the PIC32MX family.
|
|
|
|
|
* arch/arm/src/stm32/stm32_gpio.c: Correct an error in some of the GPIO
|
|
|
|
|
initialization logic. Fix submitted by Mike Smith.
|
|
|
|
|
* configs/olimex-lpc1766stk/src/up_leds.c: Add new interfaces so that is
|
|
|
|
|
CONFIG_ARCH_LEDS are not set, the LEDs may be controlled from application
|
|
|
|
|
logic.
|
|
|
|
|
* configs/olimex-lpc1766stk/src/up_buttons.c: Add support form the buttons
|
|
|
|
|
on the Olimex LPC1766-STK board.
|
|
|
|
|
* Makefile: Added 'apps_clean' and 'apps_distclean' target to simplify
|
|
|
|
|
managing the state of the application directory while in the NuttX directory
|
|
|
|
|
* Documentation/NuttXGettingStarted.html: Added a "Getting Started" Guide
|
|
|
|
|
for NuttX. At present, this is just a stub and it refers to the NuttX
|
|
|
|
|
top-level README.txt file which is the only, real "Getting Started" Guide
|
|
|
|
|
that exists at the time being.
|
|
|
|
|
* arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct an value used as the lower
|
|
|
|
|
end of an IRQ number range test.
|
|
|
|
|
* arch/arm/src/lpc17xx/lpc17_gpio.c: Fix a integer flow problem in shift.
|
|
|
|
|
This error would prevent pins > 15 from being used as interrupt sources.
|
|
|
|
|
* arch/arm/src/stm32/stm32_can.c: The CAN driver has been verified in
|
|
|
|
|
loopback mode on the STM3240G-EVAL board.
|
|
|
|
|
* configs/stm3240g-eval/src/up_adc.c: Complete coding of ADC support for the
|
|
|
|
|
potentiometer on board the STM3240G-EVAL.
|
|
|
|
|
* arch/arm/src/lpc17_can.c: Several CAN driver improvements. Adds support for
|
|
|
|
|
testing in loopback mode. now uses all three transmit buffers for better
|
|
|
|
|
performance.
|
|
|
|
|
* confgs/olimex-lpc1766stk/nsh: Now supports the CAN loopback test as an
|
|
|
|
|
optional "built-in" application.
|
|
|
|
|
* sched/irq_attach.c: Fix an issue with disabling interrupts when they are
|
|
|
|
|
detached. For the PIC32, this can't be done because there is a 1-to-many
|
|
|
|
|
relationship between vector numbers and interrupt numbers or different.
|
|
|
|
|
Added a new configuration option CONFIG_ARCH_VECNOTIRQ to at least flag
|
|
|
|
|
the architectures that have this issue and to (at least) avoid doing
|
|
|
|
|
something too wrong.
|
|
|
|
|
* drivers/can.c: Fix a test for buffer full in the generic, "upper half",
|
|
|
|
|
can driver.
|
|
|
|
|
* arch/arm/src/lm3s: Add support for the LM3S6432S2E (Contributed by Mike Smith)
