This article describes specifics for the CMSemicon BAT32G1xxGx evaluation boards.

BAT32G133-EVB

BAT32G157-EVB

PICTURE will follow

Minimum requirements

  • J-Link software V7.__b or later

Preparing for J-Link

  • Solder Header to the board (row on the side of the Chip)
Device Side J-Link Signal Pin
CLK SWCLK 9
DAT SWDIO 7
RST RESET 15
GND GND 4
VDD VTRef 1

You can use the following command line:

./JLink.exe -Device BAT32G157GK -If SWD -Speed 4000 -autoconnect 1

In case of BAT32G157GK - for other devices adopt the -device setting.

The output should look as follows:
400px

Example Project

The following example project was created with the SEGGER Embedded Studio project wizard.
As the option bytes resides in the normal flash area it's not a good idea just to compile and flash.
Make sure that the option bytes are configured in a valid configuration.
In case of the example programs this has been done by modifying the Cortex_M_Startup.s with the following code:

  .section .vectors, "a"
  // fill to 0xC0 for the flash configuration field
  //.fill 0xC0-(_vectors_end-_vectors), 1, 0xFF
  .org 0xC0, 0xFF
  // 0xC0: WDT Control BYTE
  // 0xC1: LVD Control BYTE (C1H)
  // 0xC2: HOCO Control BYTE (FRQSEL)
  // 0xC3: Flash Protect Control BYTE
  // 0xC4: Boot Area Control BYTE
  // 0xC5: QSPI flash protect option BYTE
  // 0xC6: QSPI flash protect option BYTE0
  // 0xC7: QSPI flash protect option BYTE1
  OptBytes:
  .byte 0xEF, 0xFF, 0xF0, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF

It is a simple Hello World sample linked into the internal flash.
