Failed boot

[faronov]

If I compile with make test, it works but after restarted all demo wont boot

do a flash erase and then try re-flash, in my experience this means the flash has't written correctly or been written to the wrong address

[faronov]

I erase_flash and reflash but this didn't help

[faronov]

I try some examples from esp-open-rtos like dht_sensor it works perfectly and also works after restart and(or) reset

what is mean pbuf too big ?

[maximkulkin]

"pbuf too big" means that mDNS request message was too big to handle and was dropped. mDNS library I use tries to have smaller memory footprint, thus it puts constraints on input buffers. AFAIK should not cause too much problems.

@faronov I had this same problem using an ESP-01. The units I had have a 4MB flash and the examples default to a 32MB flash. If you edit the Makefile of the example and change the FLASH_SIZE variable to match your board, it should work. Good luck!

@jmarchewka, please note that B stands for BYTE and b for bits. ESP-01 uses 4 Mb and ESP-12 uses 4MB which is 32Mb

@HomeACcessoryKid so I was wrong before, in that my ESP-01 uses a EON_EN25Q80 for flash memory which, according to the datasheet, is 8 Mb (1MB). The -flash_size parameter for esptool.py is specified in bytes. If I set FLASH_SIZE to 1, the elf2image mode of esptool.py will fail (see below). So I am a bit confused about what exactly is happening (ie, why 4 or 8 works but 32 doesn't).

[HomeACcessoryKid]

esptool uses bits to specify flash size (suggested by m instead of M), so I think you should specify

FLASH_SIZE = 8

I myself have just made an ZemiSmart RGBW bulb to work which also has 25Q80 I had to do erase_flash first before it started to behave and I used

export HOMEKIT_SPI_FLASH_BASE_ADDR=0x7A000

to define the location of the pairing info.

What is odd is that I have an ESP-01 from 2015 and it uses a 4Mb flash...

[faronov]

I use esp-07 and looks like it also have 8m flash size
