SDK 1.0.1 and 8MBit Flash?

[baoshi]

The recently released SDK 1.0.1 has this line in the readme file:

*NOTICE*: If you use Esp Flash Download Tool, please MAKE SURE to choose FLASH SIZE to 8Mbit.

I found most of the existing modules are having a 4Mbit flash (2504QBT).

Does it means AT firmware later than 1.0.1 is unable to run on current modules?

(My experiment shows it runs OK), but what are the catches?

Same as @taribo, I don't want to use upgrade over WiFi, so I still use the latest AT_v0.23 on 512KB flash

I compiled the AT source code:
On STEP 1: I choose boot version: 2=none
On STEP 2: I choose bin generate: 0=eagle.flash.bin+eagle.irom0text.bin
On STEP 5: I choose spi size: 1=512KB

I burned the .bin generated to addresses:
eagle.flash.bin-------->0x00000
eagle.irom0text.bin---->0x40000

All seems to work ok.
