The command AT+CWMODE_DEF not stores correctly in Flash

[marcoleo]

The command AT + CWMODE_DEF not stores correctly in Flash.
Turning off and on the module, setting is lost (after 2 times?)
I suppose that the problem also involves other commands

Power ON

AT+RST

It seems a problem of flash
I loaded my flash (25Q40 = 512K) as follows:

SPI Flash Config
Crystal Freq: 26M
SPI Speed 40Mhz
SPI Mode QIO
8Mbit Flash SIZE
SpiAutoSet -

boot_v1.4(b1).bin;0x0000;
user1.1024.new.2.bin;0x1000;
user2.1024.new.2.bin;0x41000;
blank.bin;0x7E000;

My flash address is correct?
Thanks in advance!

Hi,

Download and unzip the SDK_v1.1.0 http://bbs.espressif.com/viewtopic.php?f=5&t=481

You could find "4A-ESP8266__AT Instruction Set" in folder "document", "1. Preambles" shows the downloading address.

Choosing 1024KB flash:
boot_v1.4(b1).bin;0x0000;
user1.1024.new.2.bin;0x1000;
blank.bin;0x7E000 and 0xFE000

Thanks for your interest in ESP8266 !

Programmed 25Q40 (512KB)

Choosing 1024KB flash:
boot_v1.4 (b1) .bin; 0x0000;
user1.1024.new.2.bin; 0x1000;
blank.bin; 0x7E000 and 0xFE000 <== ok

The problem persists.
After the first cycle power OFF/ON CWMODE = 3 (OK)
After the second cycle power OFF/ON CWMODE = 2 (BAD !!)

Hi,

Sorry that I didn't make myself clear.

AT_v0.22（based on SDK_v1.0.0）and version before， need to programm as 512KB flash，download as 512KB flash

AT_v0.23（based on SDK_v1.0.1）and later version，need to use actually 1024KB flash，programming as 1024KB flash，downloading as 1024KB flash

If your flash is 512KB, here is a method to use latest AT firmware http://bbs.espressif.com/viewtopic.php?f=16&t=400&start=10#p1599

So sorry for the inconvenience.

Thanks,
but i think espressif should release any version of precompiled firmware so users with esp modules with 512k flash can still use latest firmware.
