Now, I have a trouble while upgrading ESP8266 firmware.
I use DIO(not QIO) only SPI Flash.
I wrote my own firmware download program according to esp8266-sdk_application_note_firmware_download_protocol_en.pdf.
The process I have done are as follows.
Sync Frame Send and receive ack(cmd 08)
Configure SPI Params(cmd 0b) and receive ack
Flash download start(cmd 02) and receive ack
N * File Packet Send(cmd 03) and receive ack
(3~4 steps are repeated for 3 times, as I wrote 3 files(eagle.flash.bin, eagle.irom0text.bin, esp_init_data_default_v08.bin)
Flash Download Stop(cmd 04)
After all processes done, esp8266 module not boots correctly.
As far as I can see, the field of SPI mode in File Header has changed to 0(QIO).
Originally sent value was 2(DIO), but when I read SPI flash using another tool I can see 0(QIO).
Would you please let me know why it has changed to QIO mode?
And is there any other way to set it as DIO?
