Part Number: TMS570LC4357

Hello,

Can someone point me in the direction to Implementing Z Modem Bootloader for TMS570LC4357.

Is there any Code or Library available?

I could find the Bootloader for Y Modem for TMS570LC4357.

Hi Sakti,

We provide example code for uart bootloader which uses ymodem.

Hello Jagadish,

Thank You for the reply. I can use this Bootloader to Flash Application.

I am looking for z-modem Bootloader or something similar as I am looking to Implement Bootloader where UART Data Receiving can be done in an Periodic manner and not using an endless while loop. Please let me know If you can help me here.

Thanks and Regards,

Sakti

I am already successful in flashing Application using ymodem as per the Bootloader example code given by you.

The next step for me is to try to flash the Application using Periodic Tasks.

I can see that ymodem does not have capability to receive the Data packets in Periodic task but does it in a while loop as shown below.

I wish to flash the Application in a periodic task (500ms) and was looking for a protocol that does so. It looks like it may be possible in Z-modem. Therefore I am looking for z-modem based Bootloader or something similar. Please let me know of any protocol or method where I can achieve it.

Thanks and Regards,

Sakti
