Hi all,
am working on openSDA of TRK KEA128 development board. I wanted to make my own openSDA board so that I could flash my MCU which is used in my project, I referred the schematics of TRK KEA 128 and designed a board with same components being used as of TRK KEA 128. I am finding few difficulties while flashing.
1. First of all when I connect it via USB to my computer it doesn’t detect ( using Code warrior to flash and debug).
2. Flashing happens once I do with development board (by connecting UART_TX, UART_RX, SWD_DIO, SWD_CLK and RESET ) but not from my board ( by connecting UART_TX, UART_RX , SWD_DIO, SWD_CLK and RESET).
3. Observation done from my board is that LED doesn't glowing once I connect USB.
Does openSDA controller IC needs to be flashed ??
Hi Jashan,
Yes, After be programmed with the firmware, the OpenSDA hardware can turn into the debug tool, and you can learn the more detail information through the link as below.
OpenSDAv2
Have a great day,

Hi jermyzhou,
Thanks for the reply, i am getting the firmware for K20 but not for M20. is there a link for it ?? and also once i connect the USB to my openSDA un-flashed board its not detecting, so i couldnt see any BOOTLOADER drive in my system ? is there anything which i have to do before pressing RESET and plugging the USB ??
Hi Jashan,
The M20AGV is the product number of the following chips.

For the KEA 128, now the OpenSDAv2 hasn't supported the device now, however the P&E Micro has the copy right of the OpenSDA and it's not the open source.
So I'm afraid it's hard to copy the OpenSDA interface from the TRK-KEA128 board.
Have a great day,
