Hi TI team

My Hub have two chips[wifi chip is QCA4531,zigbee chip is CC2538 as a coordinator].the CC2538 send and receive data to 4531 use USB interface.

1.I have achieved the CC2538 upgrade online using SBDemo tools.But now if I want to upgrade online CC2538 firmware,I should change hardware(USB interface to UART interface)?

And I want to know,I have another way to achieve CC2538 upgrade online if I am unnecessary to change the hardware?

2.If I want to achieve the end device(CC2652) ota[CC2538 ota to CC2652], the end device(CC2652) must have a external spi flash[storage a CC2652 bin files],and CC2538(coordinator) also?

3.How to use the zigbee linux gateway ?

Thanks!

1. To use CC2538 serial bootloader, you can refer to http://www.ti.com/lit/an/swra466b/swra466b.pdf and yes, serial bootloader uses UART or SPI.

2. To achieve the end device(CC2652) ota, you need external flash for CC265.

3. After you download Z-Stack Linux GW reference design, there are user guides in document folder.

OK! Thanks YiKai Chen,

1.It mean that my Hardware should be chanage(USB to UART).

2.To achieve the end device(CC2652) ota, you need external flash for CC2652. the CC2538 had no need to it.

3.I will learn more about the PDF you say it.

Thanks!
