|

Creating and Using NORBOOT
|
||||
==========================
|
||||
|
||||
In order to have more control of debugging code that runs out of NOR FLASH,
|
||||
I created the sama5d3x-ek/norboot configuration. That configuration is
|
||||
described below under "Configurations."
|
||||
|
||||
Here are some general instructions on how to build an use norboot:
|
||||
|
||||
Building:
|
||||
1. Remove any old configurations (if applicable).
|
||||
|
||||
cd <nuttx>
|
||||
make distclean
|
||||
|
||||
2. Install and build the norboot configuration:
|
||||
|
||||
cd tools
|
||||
./configure.sh sama5d3x-ek/<subdir>
|
||||
cd -
|
||||
. ./setenv.sh
|
||||
|
||||
Before sourcing the setenv.sh file above, you should examine it and
|
||||
perform edits as necessary so that TOOLCHAIN_BIN is the correct path
|
||||
to the directory than holds your toolchain binaries.
|
||||
|
||||
3. Rename the binaries. Since you will need two versions of NuttX: this
|
||||
norboot version that runs in internal SRAM and another under test in
|
||||
NOR FLASH, I rename the resulting binary files so that they can be
|
||||
distinguished:
|
||||
|
||||
mv nuttx norboot
|
||||
mv nuttx.hex norboot.hex
|
||||
mv nuttx.bin norboot.bin
|
||||
|
||||
4. Build your NOR configuration and write this into NOR FLASH. Here, for
|
||||
example, is how you would create the NSH NOR configuration:
|
||||
|
||||
cd <nuttx>
|
||||
make distclean # Remove the norboot configuration
|
||||
cd tools
|
||||
./configure.sh sama5d3x-ek/nsh # Establish the NSH configuration
|
||||
cd -
|
||||
make # Build the NSH configuration
|
||||
|
||||
Then use SAM-BA to write the nuttx.bin binary into NOR FLASH. This
|
||||
will involve holding the CS_BOOT button and power cycling to start
|
||||
the ROM loader. The SAM-BA serial connection will be on the device
|
||||
USB port, not the debug USB port. Follow the SAM-BA instruction to
|
||||
write the nuttx.bin binary to NOR FLASH.
|
||||
|
||||
5. Restart the system without holding CS_BOOT to get back to the normal
|
||||
debug setup.
|
||||
|
||||
6. Then start the J-Link GDB server and GDB. In GDB, I do the following:
|
||||
|
||||
(gdb) mon reset # Reset and halt the CPU
|
||||
(gdb) load norboot # Load norboot into internal SRAM
|
||||
(gdb) mon go # Start norboot
|
||||
(gdb) mon halt # Break in
|
||||
(gdb) mon reg pc = 0x10000040 # Set the PC to NOR flash entry point
|
||||
(gdb) mon go # And jump into NOR flash
|
||||
|
||||
The norboot program can also be configured to jump directly into
|
||||
NOR FLASH with out requiring the the final halt and go, but since I
|
||||
have been debugging the early boot sequence, the above sequence has
|
||||
been most convenient for me.
|
||||
|
||||
STATUS:
|
||||
2013-7-30: I have been unable to execute this configuration from NOR
|
||||
FLASH by closing the BMS jumper (J9). As far as I can tell, this
|
||||
jumper does nothing on my board??? So I have been using the norboot
|
||||
configuration exclusively to start the program-under-test in NOR FLASH.

The OS test configuration is basically functional, but takes a very

many minutes. No idea why yet. The best guess would be an excessive

number of context switches.
