KEA128 CAN Bootloader

irmantasbudrys — Mon, 02 Jan 2017 19:17:27 GMT

Hello All,

I have downloaded code from this link: KEA128 CAN Bootloader. I am using 2 x FRDM DEV BRD KEAZ, KDS and Tera Term. Later I would like to port code from KDS to S32. Problem is that code originally was written for different micro and different boards. Below Com12 picture shows that Bootloader_KEA_128 board sends. It looks that bootloader is working on Bootloader_KEA_128 board. Picture Com7 shows UART_CAN terminal where I am trying unsuccessfully to send LED_D3_demo.bin file. I think it is not working and I don't know that is wrong with it.

Questions:

a) Could anyone help me? (For UART to PC communication I am using FRDM DEV BRD OpenSDA) .

b) Does anyone knows where to get UART bootloader for KEA 128 code? Or maybe other micro code which could be easily ported to KEA128?

Best Regards,

Irmantas

Hello Irmantas,

For the bootloader KEA128 CAN Bootloader.

As to the board K20 OpenSDA debugger cannot meet the boot loader transmit speed requiremtns,

so you need use UART port connect to an external UART-USB , then connected to PC USB port .

Hello,

I have ported UART-CAN code to KEA128 and it is not working. XMODEM doesn't transmit .bin file via UART.

Is where any working examples for KEA?

Code is written in complicated manner... I can't find where UART configuration is in UART-CAN(channel, speed,pin number for UART etc) code?

Best Regards,

Irmantas

Hello Irmantas,

- There are other ports bootloader for KE chips, it can easy porting to KEA:

KEA 128 Boot loader

Uart bootloader

- About UART-CAN, the CAN configuration code is in the function :

UART_InitPrint();

For professionals who have real work to do rather than port boot loaders, most are already available at
http://www.utasker.com/kinetis.html

For the KEA128 ready-made (work out of the box, fully tested and supported, and can be built with almost any IDE - including KDS and S32) UART and KBOOT loaders are available:
