blank.bin 0x7E000
boot_v1.6.bin 0x00000
at\...\user1.1024.new.2.bin 0x01000
I set:
crystalfreq to 26M
SPI speed to 40MHz
Flash size to 8Mbit
proper com port
baudrate to 115200

After i set ESP to flash mode i hit START. All gone ok with last lines on terminal:
writing at 0x000fc000... (99%)
leaving...
com closed

And on download tool i get massage Finish. I pressed reset on my ESP and after that i started Serial to check the result. But there is nothing.
When i disconnect CH_PD for a sec i get: ets Jan 8 2013,rst cause: 1, boot mode:(1,7) which i think indicates not enough power.

I power ESP with external power supply on 9V 600mA step down with XL4015 to 3,3V which i checked with multimeter.

No it doesn't work or i didn't do something right. Any help would be nice.
