【Feedback】-C1 designation from readme.txt in SDKv1.4\bin\at

[Drummond]

the following is from the Readme.txt file in \bin\at\ could you explain what the -C1 indicated? Maybe I am missing something somewhere, but I am not finding any indication as to what the difference is for this.

Thank you for your help and patience,

Hi,

"16Mbit-C1" and "32Mbit-C1" are the options of Flash size on Espressif Official Flash Download Tool.

Please use Espressif Official Flash Download Tool to download firmware into Flash.

Thanks for your interest in ESP8266 !

How do I know if I have a -C1 flash or not?

Hi，
if you compile your Applicaton choose 5/6 in step 5, that's mean your "choose spi map" is 1024KB
