CC3130: Sending a format command for formatting the external flash

Part Number: CC3130
Other Parts Discussed in Thread: CC3100, CC3135, CC3120

I've succeded in making the break signaling over uart to our CC3130.

After this I can get version and start programming the external flash.

But according to other specs, a doc swra658.pdf chapter 16, it should be possible to format the external flash, however when trying this I always get a NACK back from the TI.

Do you have any idea why ?

We are using a WINBOND: W25Q16JVUXIQ (16 Mbyte flash). sending cmd:

0x00,0x17,0x3C,0x28,0x00,0x00,0x00,0x02,0x00,0x00,0x10,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

0x00,0x00,0x02

I've also tried other format commands, but get NACK everytime.

The document you are referring is very old and was used with CC3100.

For CC3120/CC3130/CC3135 - we recommend that you will refer to the embedded programming doc (https://www.ti.com/lit/an/swpa231/swpa231.pdf?ts=1631200917701&ref_url=https%253A%252F%252Fwww.google.com%252F)

Thanks for document, it is exactly that one I've used to implement the uart handling. Just thought I needed to format the flash the first time.

So there are no way of formatting the external flash anymore ?, or is this irrelevant when using FS programming Command (Opcode 0x34)

Yes, the FS programming command starts by formatting the flash.
