- Sun Dec 21, 2014 5:41 pm #5357 I tested a firmware version 0.9.2 build 2014-12-19 on the modified module.

1)

Firmware 512k-flash, 1M-flash and 2M-flash, recorded as one file, run and work. 2M-flash firmware and 4M-flash, recorded a set of files, do not work - via UART issued continuously:
ERROR in flash_read: r=1 at 40280000
ERROR in flash_read: r=1 at 40281000
ERROR in flash_read: r=1 at 40282000
ERROR in flash_read: r=1 at 40283000
.........
To write firmware used ESP8266Flasher and XTCOM_UTIL. The result is the same.

2)

To check how to write the files (on working firmware) i used these scripts:

Code: Select allfor j=1,50 do
  file.open("10K"..j..".txt", "w")
  for i=1,640 do
    file.writeline('0123456789ABCDE')
  end
  file.close()
end

THE RESULT:

Recording took place until the moment when the module is reloaded. After the reboot, the files can not be removed using "file.remove".

512k-flash firmware allows you to record a set of files with a total size of 100 KB:

10K6.txt size: 10240
10K2.txt size: 10240
10K4.txt size: 10240
10K8.txt size: 10240
10K1.txt size: 10240
10K10.txt size: 9984
10K7.txt size: 10240
10K9.txt size: 10240
10K3.txt size: 10240
10K5.txt size: 10240

1M-flash firmware allows you to record a set of files with a total size of 300 KB:

100K1.txt 102400 bytes
100K2.txt 102400 bytes
100K3.txt 101120 bytes

30K9.txt 30720 bytes

2M-flash firmware allows you to record a set of files with a total size of 773 KB:

100K5.txt 102400 bytes
100K4.txt 102400 bytes
100K8.txt 72192 bytes

to flash firmware other than 512k, chose flash size in Flash tool.
