ESP8266 not working properly after replacing flash chip
Posted: Thu Feb 23, 2017 4:25 pmI just replaced the 8Mb Berg Micro 25Q80 SPI flash chip on my ESP8266 ESP-03 with a 16Mb Windbond W25Q16JVSNIQ chip. ESPTOOL.py correctly identifies it as 4014, and both my Arduino and Native SDK IDEs can successfully upload to it (or at least it appears to - there are no errors). I soldered the chip correctly - I checked! Programs always ran correctly before the new flash chip.
However, the ESP8266 does not run the program now. Nothing on the serial port, and the WS2812 LEDs attached produce random colors.
I changed the flash size map to 2048KB (1024KB + 1024KB), and also tried 2048KB (512KB + 512KB), but they didn't work.
Is there something that I need to do to - upload something I'm not, some other setting - or did I inadvertently kill my ESP8266?
Thank you for your help, Ygneh
