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 |
- Power the board via USB
- Verify the Connection with e.g. J-Link Commander.
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.
