The default behavior of the NOR boot program is to initialize the

program with GDB. An alternative behvior is enabled with this
option: If SAMA5D3XPLAINED_NOR_START is defined, then it will not wait but
will, instead, immediately start the program in NOR FLASH.

Creating and Using NORBOOT
==========================
In order to have more control of debugging code that runs out of NOR FLASH,
I created the sama5d3-xplained/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. This steps will establish
the norboot configuration and setup the PATH variable in order to do
the build:
cd tools
./configure.sh sama5d3-xplained/<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.
NOTE: Be aware that the default norboot also disables the watchdog.
Since you will not be able to re-enable the watchdog later, you may
need to set CONFIG_SAMA5_WDT=y in the NuttX configuration file.
Then make norboot:
make
This will result in an ELF binary called 'nuttx' and also HEX and
binary versions called 'nuttx.hex' and 'nuttx.bin'.
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 sama5d3-xplained/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 without requiring the final halt and go by setting
CONFIG_SAMA5D3XPLAINED_NOR_START=y in the NuttX configuration. However,
since I have been debugging the early boot sequence, the above
sequence has been most convenient for me since it allows me to
step into the program in NOR.
7. An option is to use the SAM-BA tool to write the NORBOOT image into
Serial FLASH. Then, the system will boot from Serial FLASH by
copying the NORBOOT image in SRAM which will run and then start the
image in NOR FLASH automatically. This is a very convenient usage!
NOTES: (1) There is jumper on the CM module that must be closed to
enable use of the AT25 Serial Flash. (2) If using SAM-BA, make sure
that you load the NOR boot program into the boot area via the pull-
down menu.
STATUS:
2014-7-30: I have been unable to execute these configurations 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

norboot:
This is a little program to help debug of code in NOR flash. It
does the following:
- It enables and configures NOR FLASH, then
- Waits for you to break in with GDB.
At that point, you can set the PC and begin executing from NOR FLASH
under debug control. See the section entitled "Creating and Using
NORBOOT" above.
NOTES:
1. This program derives from the hello configuration. All of the
notes there apply to this configuration as well.
2. The default norboot program initializes the NOR memory,
displays a message and halts. The norboot program can also be

Since you will not be able to re-enable the watchdog later, you may

*
* "If BMS signal is tied to 0, BMS_BIT is read at 1. The ROM Code
* allows execution of the code contained into the memory connected to
* Chip Select 0 of the External Bus Interface.
*
* "To achieve that, the following sequence is preformed by the ROM
* Code:
*
* - The main clock is the on-chip 12 MHz RC oscillator,
* - The Static Memory Controller is configured with timing allowing
* code execution inCS0 external memory at 12 MHz
* - AXI matrix is configured to remap EBI CS0 address at 0x0
* - 0x0 is loaded in the Program Counter register
*
* "The user software in the external memory must perform the next
* operation in order to complete the clocks and SMC timings
* configuration to run at a higher clock frequency:
*
* - Enable the 32768 Hz oscillator if best accuracy is needed
* - Reprogram the SMC setup, cycle, hold, mode timing registers
* for EBI CS0, to adapt them to the new clock
* - Program the PMC (Main Oscillator Enable or Bypass mode)
* - Program and Start the PLL
* - Switch the system clock to the new value"

* This function provides the board-specific implementation of the logic
* to reprogram the SMC.
