I'm looking into larger flash chips for the Arachnio (https://www.kickstarter.com/projects/lo ... o/arachnio), and I was wondering if anyone could help me figure out which ones to use. 8 Mbit Winbond chips work just fine for me, but I'd like to go to a 32 MBit flash. For a test, I ordered some Spansion chips (S25FL132K0XMFI041, which is what Digikey had in stock in that size and form factor).

I flashed the chip with the 0.9.5 AT firmware using esptool. This appeared to work fine, but when I boot the chipI get the following:

Code: Select all ets Jan  8 2013,rst cause:2, boot mode:(3,3)

load 0x40100000, len 612, room 16
tail 4
chksum 0xfd
load 0x88380000, len 565951362, room 4
flash read err, ets_unpack_flash_code
ets_main.c


Any thoughts on what might be wrong here?

- Wed Apr 22, 2015 10:32 am #15289 Have you tried a power down and reflash? This frequently cures my problems when I get ets_main.c in the boot messages.

Otherwise the boot loader stopping at ets_main.c indicated a problem with the sketch, even though it compiled without errors. Now here be dragons!

I can't help with your concrete problem.

But did you notice this old chat?

They got the firmware somewhat running.

Hope that helps,

and it works.
Note that the flash size has to be set in the header of your bin file, otherwise the ESP will still treat it as a 4 MBit flash.
