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.

* Description:
|
|
||||||
* If CONFIG_SAMA5_BOOT_CS0FLASH, then the system is boot directly off
|
|
||||||
* CS0 NOR FLASH. In this case, we assume that we get here from the
|
|
||||||
* primary boot loader under these conditions:
|
|
||||||
*
|
|
||||||
* "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.
