Where <subdir> is one of the following:
knsh:
-----
This is identical to the nsh configuration below except that NuttX
is built as a PROTECTED mode, monolithic module and the user applications
are built separately.
It is recommends to use a special make command; not just 'make' but make
with the following two arguments:
make pass1 pass2
In the normal case (just 'make'), make will attempt to build both user-
and kernel-mode blobs more or less interleaved. That actual works!
However, for me it is very confusing so I prefer the above make command:
Make the user-space binaries first (pass1), then make the kernel-space
binaries (pass2)
NOTES:
1. At the end of the build, there will be several files in the top-level
NuttX build directory:
PASS1:
nuttx_user.elf - The pass1 user-space ELF file
nuttx_user.hex - The pass1 Intel HEX format file (selected in defconfig)
User.map - Symbols in the user-space ELF file
PASS2:
nuttx - The pass2 kernel-space ELF file
nuttx.hex - The pass2 Intel HEX file (selected in defconfig)
System.map - Symbols in the kernel-space ELF file
The J-Link programmer will except files in .hex, .mot, .srec, and .bin
formats.
2. Combining .hex files. If you plan to use the .hex files with your
debugger or FLASH utility, then you may need to combine the two hex
files into a single .hex file. Here is how you can do that.
a. The 'tail' of the nuttx.hex file should look something like this
(with my comments added):
$ tail nuttx.hex
# 00, data records
...
:10 9DC0 00 01000000000800006400020100001F0004
:10 9DD0 00 3B005A0078009700B500D400F300110151
:08 9DE0 00 30014E016D0100008D
# 05, Start Linear Address Record
:04 0000 05 0800 0419 D2
# 01, End Of File record
:00 0000 01 FF
Use an editor such as vi to remove the 05 and 01 records.
b. The 'head' of the nuttx_user.hex file should look something like
this (again with my comments added):
$ head nuttx_user.hex
# 04, Extended Linear Address Record
:02 0000 04 0801 F1
# 00, data records
:10 8000 00 BD89 01084C800108C8110208D01102087E
:10 8010 00 0010 00201C1000201C1000203C16002026
:10 8020 00 4D80 01085D80010869800108ED83010829
...
Nothing needs to be done here. The nuttx_user.hex file should
be fine.
c. Combine the edited nuttx.hex and un-edited nuttx_user.hex
$ cat nuttx.hex nuttx_user.hex >combined.hex
Then use the combined.hex file with the to write the FLASH image.
If you do this a lot, you will probably want to invest a little time
to develop a tool to automate these steps.
Other option is to combine nuttx.bin and nuttx_user.bin this way:
$ dd if=/dev/zero of=empty.bin bs=1k count=256
$ cat nuttx.bin empty.bin > nuttxtmp.bin
$ dd if=nuttxtmp.bin of=nuttxpad.bin bs=1k count=256
$ cat nuttxpad.bin nuttx_user.bin > nuttxfinal.bin

/* The STM32F407VG has 1024Kb of FLASH beginning at address 0x1400:0000 and
* 192Kb of SRAM. SRAM is split up into three blocks:
*
* 1) 112KB of SRAM beginning at address 0x2000:0000
* 2) 16KB of SRAM beginning at address 0x2001:c000
* 3) 64KB of CCM SRAM beginning at address 0x1000:0000
*
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
* where the code expects to begin execution by jumping to the entry point in
* the 0x1400:0000 address range.
*
* For MPU support, the kernel-mode NuttX section is assumed to be 128Kb of
* FLASH and 4Kb of SRAM. That is an excessive amount for the kernel which
* should fit into 64KB and, of course, can be optimized as needed (See
* also configs/stm32f4discovery/scripts/kernel-space.ld). Allowing the
* additional does permit addition debug instrumentation to be added to the
* kernel space without overflowing the partition.
*
* Alignment of the user space FLASH partition is also a critical factor:
* The user space FLASH partition will be spanned with a single region of
* size 2**n bytes. The alignment of the user-space region must be the same.
* As a consequence, as the user-space increases in size, the alignmment
* requirement also increases.
*
* This alignment requirement means that the largest user space FLASH region
* you can have will be 512KB at it would have to be positioned at
* 0x14800000. If you change this address, don't forget to change the
* CONFIG_NUTTX_USERSPACE configuration setting to match and to modify
* the check in kernel/userspace.c.
*
* For the same reasons, the maximum size of the SRAM mapping is limited to
* 4KB. Both of these alignment limitations could be reduced by using
* multiple regions to map the FLASH/SDRAM range or perhaps with some
* clever use of subregions.
*
* A detailed memory map for the 112KB SRAM region is as follows:
*
* 0x10000 0000: Kernel .data region. Typical size: 0.1KB
* ------- ---- Kernel .bss region. Typical size: 1.8KB
* 0x10000 0800: Kernel IDLE thread stack (approximate). Size is
* determined by CONFIG_IDLETHREAD_STACKSIZE and
* adjustments for alignment. Typical is 1KB.
* ------- ---- Padded to 4KB
* 0x10000 1000: User .data region. Size is variable.
* ------- ---- User .bss region Size is variable.
* 0x10000 2000: Beginning of kernel heap. Size determined by
* CONFIG_MM_KERNEL_HEAPSIZE.
* ------- ---- Beginning of user heap. Can vary with other settings.
* 0x10001 c000: End+1 of CPU RAM
