This release adds basic support for the STMicro STM32, Cortex-M3 MCU.
The specific port is to the STMicro STM3210E-EVAL development board based around the STM32F103ZET6 MCU.
Some highlights of this port:
The release extends the support for the STMicro STM32 microcontroller.
Minimul support for the STM3210E-EVAL development board based around the STM32F103ZET6
MCU was released in NuttX-0.4.12.
This release adds:
<ul>
<li>This basic port includes boot-up logic, interrupt driven serial console, and system timer interrupts.<li>
<li>The port includes a basic STMicro RIDE7 project that can be used to perform basic STM32 board bring-up
(due to RIDE7 size limitations, it cannot be used for the full NuttX testing, unfortunately).<li>
<li>Working, Tested Configurations: the NuttX OS test and the NuttShell (NSH) example.<li>

</p>
<p>
It is planned to extend this basic STM32 port for the 0.4.13 NuttX release.
Additional functionality needed for complete STM32 support includes:
USB device driver, LCD driver and NX bringup on the development board's display and MicroSD support.
An SPI driver and a DMA support was included in this 0.4.12 release, but is not yet tested.
This release also corrects some important bugs in the early STM32 release:
<ul>
<li>Fixed several errors the prevented operation of NuttX on an STM32 development
board using USART2 as the serial console.</li>
<li>Fixed and optimization-dependent race condition in the clock initialization.</li>
<li>Fixed a critical bug in the interrupt control logic that could cause interrupt
operations to failed used for interrupts in a certain range.</li>
</ul>
<p>
<p>
DMA and external memory support are included in the 0.4.13 release, but is not yet tested.
This basic STM32 port will be further extended in the 0.4.14 NuttX release to include
MicroSD support and verified USB mass storage class support.

* arch/arm/src/stm32 and configs/stm3210e-eval. Added basic support for the
STMicro STM32, Cortex-M3 MCU. The specific port is to the STMicro STM3210E-EVAL
development board based around the STM32F103ZET6 MCU.
* configs/stm3210e-eval/RIDE. Added a basic STMicro RIDE7 project that can be
used to perform basic STM32 board bring-up (due to RIDE7 size limitations, it
cannot be used for the full NuttX bring-up).
* configs/stm3210e-eval/ostest. The STM32 now passes the basic NuttX OS test
at examples/ostest. The rest should be a piece of cake.
* configs/stm3210e-eval/nsh. Added NuttShell (NSH) example.
* configs/stm3210e-eval/src/stm32102e-internal.h. Fix on-board LED GPIO definitions.
* arch/arm/src/stm32/src/stm32/stm32_dma.c. Added DMA channel support for the STM32
* arch/arm/src/stm32/src/stm32/stm32_spi.c. Added a DMA-based SPI driver for the STM32.
* arch/arm/src/stm32/src/stm32/stm32_serial.c. Finished interrupt-drivent,
USART console driver. This makes NSH work perfectly.
* Things left to do for the STM32 deferred to the 0.4.13 release: USB device driver,
LCD driver and NX bringup on the eval board's display and MicroSD support. An SPI
driver was included in the 0.4.12 release, but is not yet tested.
* include/nuttx/mtd.h. Added a simple interface definition to support some
FLASH, EEPROM, NVRAM, etc. devices.
* driver/mtd/m25px.c. Added a driver for SPI based FLASH parts M25P64 and M25P128.
* configs/stm3210e-eval/usbserial. Add a USB serial configuration for the STM32.
Depends on the STM32 USB driver.
* arch/arm/src/cortexm3/up_switchcontext.S & up_svccall.c. Made an improvement
to context switching. There are two types of context switches: interrupt
context switches and background/user context switches. This change should
improve the performance of those background/user context switches by a factor
of about two.
* arch/arm/src/stm32/ - fix several typos in the serial logic. It turns out
that these typose don't make any difference as long as you use only one
serial port and all uarts are configured the same. But the typos are bugs
waiting to happen in any other configuration.
* arch/arm/src/stm32/ - You have to configure CTS/RTS function pins for USART
2 and USART 3 even if you are not using flow control.
* arch/arm/src/stm32/stm32_usbdev.c - Added a USB device-side driver for the
STM32. NOTE: This is an early release of the USB driver. There is at least
one known issue. The examples/usbserial test only executes correctly under
certain conditions (see the full bug description in the TODO list).
* arch/arm/src/stm32/stm32_rcc.c - Fixed an error in clock initialization.
On some boards (none of mine), the HSE (high speed external clock) delay
loop times out if the optimization level is high. The STM32 then falls
back to the HSI (internal clock), and the system clock is too slow by a
factor of 11.1%. This was fixed by simply add the volatile storage class
to the timeout loop counter
* arch/arm/src/stm32/stm32_irq.c - Fixed a critical bug in the interrupt
control logic. The wrong register was being used for interrupts in a
certain range. Worked fine until you try to use an interrupt in that
range!

Status: Open

Description USB device-side driver
Description A USB device-side driver is in place but not well tested. At
present, the examples/usbserial test sometimes fails. The situation
that causes the failure is:
- Host-side of the test started after the target side sends the
first serial message.
The general failure is as follows:
- The target message pends in the endpoint packet memory
- When the host-side of the test is stated, it correctly
reads this pending data.
- an EP correct transfer interrupt occurs and the next
pending outgoing message is setup
- But, the host never receives the next message
If the host-side driver is started before the first target message
is sent, the driver works fine.
