README
|
||||
======
|
||||
|
||||
This README file discusses the port of NuttX to the Raspberry Pi Zero.
|
||||
The Raspberry Pi Zero is based on the Broadcom BCM2835 CPU. This is the
|
||||
same Broadcom chip used in the Raspberry Pi Model A, B, B+, the Compute
|
||||
Module.
|
||||
|
||||
STATUS
|
||||
======
|
||||
|
||||
2017-10-09: This is a work in progress. The port is not complete and
|
||||
will not build to completion. Missing logic includes:
|
||||
|
||||
- GPIO support,
|
||||
- System timer initialization, and
|
||||
- Serial driver.
|
||||
|
||||
2017-10-19: Much of that logic is in place but there are a few things
|
||||
still missing.
|
||||
|
||||
- Mini-UART Baud divisor calculation,
|
||||
- Start-up logic. My understand from what I have read on the Internet
|
||||
is the PiZero OS starts up in hypervisor mode with the MMU and I- and
|
||||
D-Caches enabled. This probably means that the standard, classic ARM
|
||||
startup logic at at arch/arm/src/arm/up_head.S will need to be replaced
|
||||
with some custom logic.
|
||||
|
||||
No testing has yet been performed.
|
||||
|
||||
Basic Setup
|
||||
===========
|
||||
|
||||
+------------+
|
||||
| |
|
||||
| +--+
|
||||
| USB | | <----------------------------> USB Power Source
|
||||
| +--+ +------------+
|
||||
| | | +--+
|
||||
| +--+ | | | <---> Keyboard
|
||||
| USB | | <-------->| USB +--+
|
||||
| +--+ | HUB |

| |
|

+------------+
|
||||
|
||||
You might be able to use the hub to power the Pi Zero, but I was not
|
||||
able to do that; my hub would not switch on power until it was enumerated
|
||||
by the host (the Raspberry Pi Zero), but then I could not power the Pi
|
||||
with the hub because it was not providing power. Chicken'n'Egg.

NuttX Boot Sequence
|
||||
===================
|
||||
|
||||
To be provided.
|
||||
|
||||
Configurations
|
||||
==============
|
||||
|
||||
Information Common to All Configurations
|
||||
----------------------------------------
|
||||
Each Raspberry Pi Zero configuration is maintained in a sub-directory
|
||||
and can be selected as follow:
|
||||
|
||||
tools/configure.sh [OPTIONS] pizero/<subdir>
|
||||
|
||||
Where [OPTIONS] include -l to configure for a Linux host platform and
|
||||
-c means to configure for a Windows Cygwin host platform. -h will give
|
||||
you the list of all options.
|
||||
|
||||
Before building, make sure the PATH environment variable includes the
|
||||
correct path to the directory than holds your toolchain binaries.
|
||||
|
||||
And then build NuttX by simply typing the following. At the conclusion of
|
||||
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||||
|
||||
make
|
||||
|
||||
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||||
must be is one of the following.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. These configurations use the mconf-based configuration tool. To
|
||||
change any of these configurations using that tool, you should:
|
||||
|
||||
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||||
see additional README.txt files in the NuttX tools repository.
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
Configuration Sub-directories
|
||||
-----------------------------
|
||||
|
||||
nsh:
|
||||
|
||||
This simple configuration directory provide the NuttShell (NSH).

* arg - The boardctl() argument is passed to the board_app_initialize()

* implementation without modification. The argument has no

* meaning to NuttX; the meaning of the argument is a contract
|

* between the board-specific initalization logic and the
|
||||
* matching application logic. The value cold be such things as a

||||
* mode enumeration value, a set of DIP switch switch settings, a

* pointer to configuration data read from a file or serial FLASH,
|
||||
* or whatever you would like to do with it. Every implementation

* should accept zero/NULL as a default configuration.

*
|
||||
* Returned Value:
|

* Zero (OK) is returned on success; a negated errno value is returned on
