Part Number: CC3220
I’m facing a trouble to program the SFLASH via UART by using Embedded Programming.
Referring document is “CC3120 and CC3220 SimpleLink™ Wi-Fi® Embedded Programming” at www.tij.co.jp/.../swpa230.pdf.
I think, from STEP1 to STEP10 are completed correctly, because an acknowledge “Last Status response:0x40” is backed by Get Status Command.
After that, Wi-Fi FW USF file which is created by using Image Creator is programed as STEP11.
However image is not programed properly.
Question1: What’s the format to program the SFLASH? (UCF?)
Question2: I send the data with the following format at once. Is it correct?
Packet size: 2byte (4096)
Checksum: 1byte
FS Programming command: 1byte(0x34)
Key size: 2byte (0)
Chunk size: 2byte (4096)
Flags : 4byte (0)
Data : 4084 byte(FW)
Question3: Could you please advise me the points which I confirm to solve it.
