- Wed Aug 26, 2015 8:09 am #27085 Hello Lethe,
I am compiling the code using lubuntu .After the make file,./gen_misc.sh has 5 modes. I am selecting modes is step 1:boot_v1.1
step 2:eagle.flash.bin+eagle.irom0text.bin
step 3: spi speed-40MHz
step 4: spi mode-DIO
step 5: spi size and map-4096KB
And at the end upload the code throught ESP flash downloader Tool
Then also having same issue

��n't use rtc mem data


The last line says "don't use rtc mem data" but I don't see this string in my code or the SDK. Any other ideas? Or is this just a busted batch of ESP-12Es?

- Sat Aug 29, 2015 12:46 am #27293 @trendchaster: setting the flash mode with the gen_misc.sh script does not help, if the flash tool screws with those setting...

@rith87: I'd suggest you completely erase the flash, reflash esp_init_data_default.bin and try a known working firmware image.
