LPC-LINK2 Debug Probe Firmware update required¶

tested on Windows 7

Based on

https://os.mbed.com/platforms/LPCXpresso54608/

and

https://os.mbed.com/teams/NXP/wiki/Updating-LPCXpresso-firmware

you need to update your LPCXpresso (programmer/debugger) to the latest firmware to enable the mbed flash disk interface.

Note that for LPCXpresso54114 and LPCXpresso546xx boards there is a 2-step programming process (first bootloader needs to be installed, then binary for LPC546xx board).

Detailed guide as follows:

1. Go to LPCScrypt webpage and download its latest version (needs admin rights)

• https://www.nxp.com/lpcscrypt

2. Go to DOCUMENTATION section of above link and select “LPC-Link2 Debug Probe Firmware Programming”

• https://www.nxp.com/docs/en/supporting-information/Debug_Probe_Firmware_Programming.pdf
• Please see page 3. for instructions

3. Configure the selected board to DFU Boot, then connect to the host computer via USB

• In case of: OM13092/LPCXpresso54806
  • check jumper JP5 “DFU LINK” (needs to be installed) – to download firmware from IDE

4. Download Link2 (LPC432x) Bootloader binary (Use this Bootloader first for boards that require a 2-step update)

• https://os.mbed.com/media/uploads/mmahadevan/lpc4322_bl_crc.bin
• Save to directory of LPCScrypt
  • C:\nxp\LPCScrypt_2.0.0_831\probe_firmware\LPCXpressoV2
  • LPCXpressoV2 folder has been chosen because I was able to find an info that debug probe LPC432x is being programmed with LPC432x_IAP_CMSIS_DAP_V5_183.bin file (and this file is in LPCXpressoV2 folder)
    • to confirm that please go to ^{Start -> start typing LPC -> choose “Program LPC-Link2 with CMSIS-DAP”}

5. Make a copy of program_CMSIS.cmd file in C:\nxp\LPCScrypt_2.0.0_831\scripts and call it program_CMSIS_mbed_daplink.cmd

• Open with Notepad++ program_CMSIS_mbed_daplink.cmd file
• edit:

before
set Link2ImageWild=LPC432x_IAP_CMSIS_DAP_*.bin

after
set Link2ImageWild=lpc4322_bl_*.bin

• or comment (by adding REM)

before
set Link2ImageWild=LPC432x_IAP_CMSIS_DAP_*.bin

after
REM set Link2ImageWild=LPC432x_IAP_CMSIS_DAP_*.bin
    set Link2ImageWild=lpc4322_bl_*.bin

6. Go to ^{Start -> cmd}

• go to directory

cd C:\nxp\LPCScrypt_2.0.0_831\scripts

• type command
  • program_CMSIS_mbed_daplink
  • because of changes in program_CMSIS_mbed_daplink.cmd, now file downloaded from MBED called lpc4322_bl_crc.bin is executed
  • ^Ctrl+C to quit

7. Disconnect the board

8. Remove the jumper JP5 “DFU LINK”

9. Connect again the board

• In that step board should be seen as MAINTANANCE

10. Go to https://armmbed.github.io/DAPLink/ and type in the box 54608, then you will see firmware file called

• 0251_lpc4322_lpc54608xpresso_0x10000.bin
• Download the firmware file
• Save wherever you want
• Drag-and-drop the firmware file onto the mounted drive called MAINTANANCE
• Wait for the file copy operation to complete
• Power cycle the board. It will now enumerate and mount as DAPLINK or the name of the board

11. Ready for drag and drop programming
