@jayc75 Use esptool.py flash_id and you will get something like
Connecting...
Manufacturer: c8
Device: 4013

Check
#define GIGADEVICE_ID0xC8/* GigaDevice */
#define GIGADEVICE_GD25T800x3114
#define GIGADEVICE_GD25Q5120x4010
#define GIGADEVICE_GD25Q100x4011
#define GIGADEVICE_GD25Q200x4012/* Same as GD25QB */
#define GIGADEVICE_GD25Q400x4013/* Same as GD25QB */
#define GIGADEVICE_GD25Q800x4014/* Same as GD25Q80B (which has OTP) */
#define GIGADEVICE_GD25Q160x4015/* Same as GD25Q16B (which has OTP) */
#define GIGADEVICE_GD25Q320x4016/* Same as GD25Q32B */
#define GIGADEVICE_GD25Q640x4017/* Same as GD25Q64B */
#define GIGADEVICE_GD25Q1280x4018/* GD25Q128B only? */
#define GIGADEVICE_GD25LQ400x6013
#define GIGADEVICE_GD25LQ800x6014
#define GIGADEVICE_GD25LQ160x6015
#define GIGADEVICE_GD25LQ320x6016
#define GIGADEVICE_GD25LQ640x6017/* Same as GD25LQ64B (which is faster) */
#define GIGADEVICE_GD25LQ1280x6018
#define GIGADEVICE_GD29GL064CAB0x7E0601
(from http://code.coreboot.org/svn/flashrom/t ... ashchips.h)

In this case it is GIGADEVICE_GD25Q400x4013/* Same as GD25QB */
40 means 4Mb = 512MB

is there a tool that can read and report the memory size of a module? or even an API?

I think esp8266 is still little unstable, making it harder to consider in applications other then prototyping or testing . It was obvious the library will grow larger than 512KB flash. I'm not saying there not doing a great job but things could be better. The thing that I don't get is why Espressif team don't make there own module??? with a real datasheet instead of everyone guessing. I volunteer to do the layout for free

you can still use modules with 512k flash, you just cannot update via cloud.

just set flash downloader to
boot_v1.3+.bin 0x00000
user1.1024.new.bin 0x01000
blank.bin 0x7e000

only the above 3 lines are checked and do not set one for 0xfe000
I kept my flash setting to 4mbit.

this is the firmware version I get after the update
AT+GMR

AT version:0.23.b1.0(Apr 2 2015 23:27:52)
SDK version:1.0.1(b1)
compile time:Apr 2 2015 23:39:06

OK

While it is good to see the AT library being extended with extra functions I think it is a BIG mistake to remove support for 512KB configurations.

As phil states most of the modules (ESP-01 etc) only come with 512 KB, so this change now rules out upgrades. I have an ESP-12 which reports 4MB, but no where did that figure appear in the sales info, so it is very difficult to know what memory a module comes with.

Please, espressif team, consider continued support for 512kB modules by producing a feature limited sub build.

Dear Esspresif Team,

you just submit ESP8266 SDK (esp_iot_sdk_v1.0.1_b1_15_04_02)

then i read :
"AT_v0.23_b1_on_sdk_v1.0.1 release note
Note: AT added some functions so flash size need to be 1024KB or more than that. "

that mean that all of near all modules available on the market can use it
as they only have 512KB of flash memory !...

regards
