• Familiar with the features of the SAM9X60_board (board can be evaluation Kit or Curiosity board) and understanding about the jumpers & Connectors in the board.
• Install SAM-BA tool on your windows host PC.
  • To Download the latest version of SAM-BA tool for Windows click this link.
  • Download the ZIP file and unzip it into a working directory of your choice.
  • Add the SAM-BA directory path to the environment variables.
    • To do this from your PC –> Open the Start Search, type in “env”.
    • Choose “Edit the system environment variables” –> Click “Environment Variables” –> “System Variables” –> add SAM-BA directory path to path variables.
  • Once the SAM-BA Host program has been installed, the execution of the application is from the Windows command prompt.
  • Now open Windows command prompt and enter the below command to ensure sam-ba is installed properly.
    sam-ba -v
    

• Refer this link to configure and build the at91bootstrap to load the application from the user preferred NVM like QSPI, NAND or SDCard.

  Note: This resultant at91bootstrap file (boot.bin) built with the preferred NVM configuration only to be used here.

• Refer this link to build harmony application.

In this section you will establish SAM-BA Host Application communications with the target’s (SAM9X60) SAM-BA Monitor. Then you will use the SAM-BA Host Applet (qspiflash) to erase and then write the boot.bin (at91bootstrap) and harmony.bin (MPLAB Harmony 3 application) binary images to NOR Flash Memory.

Step 1: To communicate with the SAM-BA Monitor on the target, you must have installed the SAM-BA Host on a Host Computer.

Step 2: Ensure there is no SD memory card inserted.

Step 3: Power the board by connecting a Micro-B USB cable to USBA port (J7) on the SAM9X60-EK or (J1) on the SAM9X60 Curiosity Development Board.

Step 4: Establish UART serial communication with PC through J24 on SAM9X60 Evaluation Kit or J11 on SAM9X60 Curiosity Development Board.

Step 5: Open Disable boot Jumper(J13) on SAM9X60 Evaluation Kit or Open the J4 NAND boot jumper on SAM9X60 Curiosity Development Board.

Step 6:

• If you are using SAM9X60 Evaluation Kit follow these steps:
  • 5.1. Push and hold the “DIS_BOOT” button.(This disables booting from the onboard memories - NAND and NOR(QSPI) flash Memory)
  • 5.2. Reset the board by pressing and then releasing the reset “nRST” button.
  • 5.3. Release the “DIS_BOOT” button.
• If you are using SAM9X60 Curiosity Development Board follow these steps:
  • 5.1. Open the J4 NAND boot jumper.(This disables booting from the NAND flash Memory)
  • 5.2. Reset the board by pressing and then releasing the reset “RESET” button.
  • 5.3. Close the J4 NAND boot jumper.

Now, the SAM9X60_board will boot to the SAM-BA Monitor and start communications with the SAM-BA Host Application.

Note:

• SAM-BA communication Port can be j-link, serial or secure.

• If user want to program the SAM9X60 Evaluation Kit, using j-link instead of serial UART port, then connect J22 with PC via USB cable and replace “serial” in SAM-BA commands with “j-link”.

  • Eg: Replace sam-ba -p serial -b sam9x60-ek -a lowlevel with sam-ba -p j-link -b sam9x60-ek -a lowlevel

1.1. Erase QSPI flash memory

sam-ba -p serial -b sam9x60-ek -a qspiflash -c erase

Example:

1.2. Program boot.bin to QSPI flash memory

Program the boot.bin file on the SAM9X60-board with the following command:

• Note: Change directory to the location of boot.bin

Example:

Note: Refer this link to configure and build the at91bootstrap to load the application from QSPI.

The at91bootstrap file (boot.bin) built with QSPI configuration only to be used here.

1.3. Program harmony.bin to QSPI flash memory

To program the application binary, harmony.bin file on the SAM9X60_board, use the following command:

sam-ba -p serial -b sam9x60-ek -a qspiflash -c write:harmony.bin:QSPI_OFFSET

Note:
* The QSPI_OFFSET should be the same offset used in the KCONFIG, while configuring the at91bootstrap to load from external QSPI
* Change directory to the location of harmony.bin.

Example:

2.1. Erase NAND flash memory

Erase the contents of the NAND Flash memory on the SAM9X60-board with the following command:

Example:

2.2. Program boot.bin to NAND flash memory

Note:
* The NAND_OFFSET should be same as the one used in the KCONFIG, while configuring the at91bootstrap to load from external NAND flash.
* Change directory to the location of harmony.bin.

Example:

Note:

To learn about more SAM-BA applet commands, refer your SAM-BA installation directory/doc/applet.html

To program the at91bootstrap -boot.bin file and application binary -harmony.bin file on SD-card:

• (i) Format the SD card using your PC/Laptop.
• (ii) Copy and paste boot.bin and harmony.bin into the SD card from your host PC.

Note: Refer this link to configure and build the at91bootstrap to load the application from SD Card.

The at91bootstrap file (boot.bin) built with SD card configuration should be used here.

After a reset, The ROM code reads the Boot Configuration Packet from the SRAM dedicated to Emulation mode if the bit BSC_CR.EMUL_EN is set to 1 or from the OTP matrix and configure boot sequence, Enable/Disable Monitor, configure the serial console UART.

Using Emulated OTP enables the user to test several boot configuration options, including secure boot mode without programming the OTP.

Note: If Emulation mode is enabled, the emulation SRAM is not backed up. After a power off/on, the configuration and content are lost.

4.1. Enable/Disable Emulation mode in BSC_CR

To Enable/Disable Emulation mode in Boot Sequence Controller Configuration Register (BSC_CR), the following SAM-BA command should be used:

//To Enable Emulation Mode:

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bscr: EMULATION_ENABLED

//To Disable Emulation Mode:

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bscr: EMULATION_DISABLED

4.2. Steps to write Boot Configuration Packet to emulated SRAM

1. Emulation enable : sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bscr:EMULATION_ENABLED
2. Reset : sam-ba -p serial -d sam9x60 -a bootconfig -c resetemul
3. Refresh config : sam-ba -p serial -d sam9x60 -a bootconfig -c refreshcfg:emul
4. Write Config : sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bcp-emul:NFC_IOSET1 // Refer section 4.4. for different configurations
5. Lock config : sam-ba -p serial -d sam9x60 -a bootconfig -c lockcfg:bcp-emul

4.3. Steps to write Boot Configuration Packet to OTP

1. Emulation disable: sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bscr:EMULATION_DISABLED
2. Refresh config : sam-ba -p serial -d sam9x60 -a bootconfig -c refreshcfg:otp
3. Write Config : sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:bcp-otp:NFC_IOSET1 // Refer section 4.4. for different configurations
4. Lock config : sam-ba -p serial -d sam9x60 -a bootconfig -c lockcfg:bcp-otp

4.4. Boot Configuration Packet- different configurations available:

The writecfg command programs the Boot Configuration Packet (BCP) into the Emulated SRAM, if the emulation mode of the OTPC is enabled. Else BCP packets are stored inside the OTP matrix.

User can use the below command to get the full list of boot configurations possible:

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg:help

Example boot configurations:

// boot config with Serial Console on FLEXCOM0, boot from SDMMC1 (PA10 as card-detect pin) store in OTP matrix

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg: bcp-otp:FLEXCOM0_USART_IOSET1,SDMMC1_IOSET1_PA10

// Empty boot configuration packet in OTP matrix

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg: bcp-otp:

// boot config with SAM-BA Monitor Disabled, boot from SDMMC1 (PA10 as card-detect pin) store in OTP-Emulation mode

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg: bcp-emul:MONITOR_DISABLED,SDMMC1_IOSET1_PA10

// Empty boot configuration packet in OTP-Emulation mode- Emulated SRAM

sam-ba -p serial -d sam9x60 -a bootconfig -c writecfg: bcp-emul:
