dram_main is a tiny program that runs in ISRAM. dram_main will
enable SDRAM and load an Intel HEX program into SDRAM over the
serial console. Then it will either (1) jump to the program in
DRAM at address 0x2000:0000 (2) wait for you to break in with GDB to
debug the SDRAM program. These different behaviors are controlled
by SAMA5D4EK_DRAM_START.
NOTE: If you use this boot loader, then your program must be built at
origin 0x2000:0000, not at 0x2100:0000 as is customary with U-Boot.

Creating and Using DRAMBOOT
===========================
In order to have more control of debugging code that runs out of DARM,
I created the sama5d4-ek/dramboot configuration. That configuration is
described below under "Configurations."
Here are some general instructions on how to build an use dramboot:
Building:
1. Remove any old configurations (if applicable).
cd <nuttx>
make distclean
2. Install and build the dramboot configuration. This steps will establish
the dramboot configuration and setup the PATH variable in order to do
the build:
cd tools
./configure.sh sama5d4-ek/dramboot
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 dramboot 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 dramboot:
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
dramboot 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 dramboot
mv nuttx.hex dramboot.hex
mv nuttx.bin dramboot.bin
4. Build the "real" DRAM configuration. This will create the nuttx.hex
that you will load using dramboot.
5. Restart the system holding DIS_BOOT. You should see the RamBOOT
prompt on the 115200 8N1 serial console (and nothing) more. Hit
the ENTER key with the focus on your terminal window a few time.
This will enable JTAG.
6. Then start the J-Link GDB server and GDB. In GDB, I do the following:
(gdb) mon heal # Halt the CPU
(gdb) load dramboot # Load dramboot into internal SRAM
(gdb) mon go # Start dramboot
You should see this message:
Send Intel HEX file now
Load your program by sending the nuttx.hex via the terminal program.
Then:
(gdb) mon halt # Break in
(gdb) mon reg pc = 0x20000040 # Set the PC to DRAM entry point
(gdb) mon go # And jump into DRAM
The dramboot program can also be configured to jump directly into
DRAM without requiring the final halt and go by setting
CONFIG_SAMA5D4EK_DRAM_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 SDRAM.
7. An option is to use the SAM-BA tool to write the DRAMBOOT image into
Serial FLASH. Then, the system will boot from Serial FLASH by
copying the DRAMBOOT image in SRAM which will run, download the nuttx.hex
file, and then start the image loaded into DRAM automatically. This is
a very convenient usage!
NOTES: (1) There is that must be closed to enable use of the AT25
Serial Flash. (2) If using SAM-BA, make sure that you load the DRAM
boot program into the boot area via the pull-down menu.
Running NuttX from SDRAM
========================
NuttX may be executed from SDRAM. But this case means that the NuttX
binary must reside on some other media (typically NAND FLASH, Serial
FLASH, or, perhaps even a TFTP server). In these cases, an intermediate
bootloader such as U-Boot or Barebox must be used to configure the
SAMA5D4 clocks and SDRAM and then to copy the NuttX binary into SDRAM.

TFTP server). In these cases, an intermediate bootloader such as U-Boot
or Barebox must be used to configure the SAMA5D4 clocks and SDRAM and
then to copy the NuttX binary into SDRAM.
The SRAMBOOT program is another option (see above). But this section
will focus on U-Boot.

be forewarned: You have only 16 seconds to run your watchdog timer test!
NOTE: If you are using the dramboot program to run from DRAM as I did,
beware that the default version also disables the watchdog. You will
need a special version of dramboot with CONFIG_SAMA5_WDT=y.

Now for the gory details:
dramboot:
This is a little program to help debug of code in DRAM. It does the
following:
- It configures DRAM,
- It loads and Intel HEX file into DRAM over the terminal port,
- Waits for you to break in with GDB.
At that point, you can set the PC and begin executing from SDRAM under
debug control. See the section entitled "Creating and Using
DRAMBOOT" above.
NOTES:
1. This configuration uses the the USART3 for the serial console
which is available at the "DBGU" RS-232 connector (J24). That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
2. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
If you are running on Linux, make *certain* that you have
CONFIG_HOST_LINUX=y *before* the first make or you will create a
corrupt configuration that may not be easy to recover from. See
the warning in the section "Information Common to All Configurations"
for further information.
3. This configuration executes out of internal SRAM flash and is
loaded into SRAM by the boot RomBoot from NAND, Serial
DataFlash, SD card or from a TFTPC sever via the Boot ROM.
Data also is positioned in SRAM.
2. The default dramboot program initializes the DRAM memory,
displays a message, loads an Intel HEX program into DRAM over the
serial console and halts. The dramboot program can also be
configured to jump directly into DRAM without requiring the
final halt and go by setting CONFIG_SAMA5D4EK_DRAM_START=y in the
NuttX configuration.
3. Be aware that the default dramboot 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.
4. If you put dramboot on the Serial FLASH, you can automatically
boot to SDRAM on reset. See the section "Creating and Using DRAMBOOT"
above.
5. Here are the steps that I use to execute this program in SRAM
using only the ROM Bootloader:
a) Hold the DIS_BOOT button and
b) With the DIS_BOOT button pressed, power cycle the board. A
reset does not seem to be sufficient.
c) The serial should show RomBOOT in a terminal window (at 115200
8N1) and nothing more.
d) Press ENTER in the terminal window a few times to enable JTAG.
e) Start the Segger GDB server. It should successfully connect to
the board via JTAG (if JTAG was correctly enabled in step d)).
f) Start GDB, connect, to the GDB server, load NuttX, and debug.
gdb> target remote localhost:2331
gdb> mon halt (don't do mon reset)
gdb> load nuttx
gdb> mon reg pc (make sure that the PC is 0x200040
