Hi ,

     There is a UART Bootloader reference please refer to below link that would be helpful for you .

Besides , a Kinetis bootloader can be download from http://www.freescale.com/kboot that also support UART interface .

Hi,

Thanks for sharing the information. It is more useful.

I am testing it now and i am facing one issue during testing. I have set the Main Application Vector address at 0x4000 and bootloader address at 0x0. But after completion of file transfer, if i press the g, it is running the bootloader application at 0x00 location. it is not executing the Actual Main Application.

Could you please suggest the solution or please provide some reference projects for both application and bootloader.  I am using CommandLineBootloader.20141120.zip  for my testing.

Regds,

Please refer as below to setting your user application memory command file(ex. ProcessorExpert.lcf),

    m_interrupts = 0x4000

    m_text= 0x4410

    m_cfmprotrom = 0x4400

Hi,

Thanks for the reply. Can i use it for K20 Series like K20, K22, K26. Are there any configuration changes required to make it compatible with that device. I am using K20 with External Crystal. 

It will be great if you can share SD Card Bootloader also.

Regards

Dhru
