Data Sheet

Interface Firmware (I/F)

Please update the interface firmware in the following way when upgrading, or if it has been deleted for some reasons.

  1. Download Flash programmer tool Flash Programmer_M366_202112.zip to program I/F firmware.
  2. Download ESP-SBK-M4KN I/F Firmware tmpm366_tmpm4kn_stk_firmware_v0254.hex

To update I/F firmware, old firmware needs to be erased before updating the firmware.

Mandatory On Board Jumper Settings

  1. Short JP6 to supply power to board
    https://os.mbed.com/media/uploads/deepakshreshti/esp-sbk-m4kn_jp6.png
  2. Short JP1 to enable DAP and short JP4 to enable SWD https://os.mbed.com/media/uploads/deepakshreshti/esp-sbk-m4kn_jp1_jp4.png

How to erase and program I/F firmware

  1. Short JP2
    https://os.mbed.com/media/uploads/deepakshreshti/esp-sbk-m4kn_jp2.png
  2. Connect PC to USB1 on SBK-M4KN by micro USB cable

  3. Start up Flash Programmer
    Click FlashProgIT.exe on your PC.
    When you use the flash programmer, you need to agree "SOFTWARE LICENSE AGREEMENT"
  4. Select [Device] tab
  5. Select Series "TX03 Series"
  6. Select Device "TMPM366FY" and push Apply button on Device tab.
  7. Select [Object File] tab and browse the downloaded ESP-SBK-M4KN Firmware
  8. Select "USB" at Communication tab and push OK button.
  9. Select [Edit]-[Chip Erase] from the menu bar.
    (If you meet password error, select [Setup] -[ Password] from the menu bar and select "Device is Blank" )
    (If you meet command error, reconnect USB cable and try [Edit]-[Chip Erase] again
  10. Once erase is completed, Select [Edit] - [Erase/Program] from the menu bar.
    (If you meet password error, select [Setup] -[ Password] from the menu bar and select "Device is Blank" )
    (If you meet command error, reconnect USB cable and try [Edit]-[Erase/Program] again
  11. Remove jumper on JP2
  12. Reconnect USB cable
    DAPLink drive will appear if I/F firmware is programmed successfully

Known issues

Warning

The latest version of "mbedls" is not able to detect the board.
The workaround is to mock the detection of the board:

mbedls --mock 7020:TMPM4KN
