- Fri Aug 14, 2015 10:57 am #25972 I never upgraded my esp-01 modules before so maybe i've done some mistake in the process but i simply flash the bin files under \bin\at folder using FLASH_DOWNLOAD_TOOLS_v1.2 with these addresses:

Code: Select allboot_v1.2+.bin         0x00000
user1.1024.new.2.bin     0x01000
blank.bin              0x7e000 & 0xfe000

and the module start but the doesn't connect or gives ip to other devices.
After that i noticed that the flash tool sees only 4Mbit so i used these other addresses:

Code: Select alleagle.flash.bin      0x00000
eagle.irom0text.bin   0x40000
blank.bin      0x3e000 & 0x7e000

That i found in a readme file.

Now the module start, accept the command but like before is not able to connect to a router or able to give ip address.

The firmware is correctly flashed since AT+GMR gives

Code: Select allAT version:0.30.0.0(Jul  3 2015 19:35:49)
SDK version:1.2.0
compile time:Jul  3 2015 20:52:41

The only strange things that is that during soft reset there is fail in the memory check

Code: Select allAT+RST


OK

Now i'm using 2 aa battery and with the old firmware everything work so i don't think this is the case but it's worth a try.
On monday i hope to have the solution.
