Hi,

Can you please let me know or guide me with some documentation, so i can perform firmware upgrade of CYW54907.

In my project no FTDI chip set like, CYW954907AEVAL1F Evaluation kit.

I am an 8 bit MCU, which uart TX & RX connected with CYW54907 RX & TX respectively.

I want to know, if i want to perform firmware upgrade like above HW setup, how i can achieve this.

by the way, i don't want to use over the air firmware upgrade.

Thank you.

With Regards.

Currently we do not have a UART bootloader available by default from WICED Studio but here are the steps that i would do if i have been given the same problem.

1. Use apps/waf/bootloader.c and merge sflash_write snip to the same.

2. Add UART write and read function to the same.

3. Use PC and write a python script to test if read and write works perfectly.

4. Convert python code in PC to corresponding driver in your 8 bit MCU and test the same.
