what files to flash for NON OS SDK

Postby n_kotso1 » Sat Jun 02, 2018 9:24 pm

Hi, I downloaded this firmware version ESP8266 NONOS SDK V2.2.0 for flashing it to my esp-12 (via wires) and use it with AT Commands. I also downloaded the latest version of Flash download tools v3.6.4. I'm in the step where I must put the paths and addresses for the files to flash. I opened the readme file from ESP8266 NONOS SDK V2.2.0 where refers to these files for NON BOOT MODE:

eagle.flash.bin 0x00000
eagle.irom0text.bin 0x10000
Flash size 8Mbit: 0x7e000 & 0xfe000
Flash size 16Mbit: 0x7e000 & 0x1fe000
Flash size 16Mbit-C1: 0xfe000 & 0x1fe000
Flash size 32Mbit: 0x7e000 & 0x3fe000
Flash size 32Mbit-C1: 0xfe000 & 0x3fe000
esp_init_data_default.bin (optional)
Flash size 8Mbit: 0xfc000
Flash size 16Mbit: 0x1fc000
Flash size 16Mbit-C1: 0x1fc000
Flash size 32Mbit: 0x3fc000
Flash size 32Mbit-C1: 0x3fc000

But my problem is that the "eagle.flash.bin" and "eagle.irom0text.bin" files are nowhere!
Any suggestions?
Is it something that I've missed?

Thank you in advance.

I'm in my other office right now, I'll check my makefile when I return to the other one to get you the locations.

Edit: Here is a custom makefile I made, I hope this helps, in a nutshell I don't use either of those files you talk about sir.

Code: Select all

CFLAGS = -I. -DICACHE_FLASH -mlongcalls

The two files "eagle.flash.bin" and "eagle.irom0text.bin" are the final outputs from the compiler.
E.g. if you use the ./gen_misc script to build your app (or one of the example), at step 2 the script will ask you if you want to generate these two files (for non-FOTA) or user1.bin or user2.bin (for FOTA):

STEP 2: choose bin generate(0=eagle.flash.bin+eagle.irom0text.bin, 1=user1.bin, 2=user2.bin)
enter (0/1/2, default 0):
ignore boot
generate bin: eagle.flash.bin+eagle.irom0text.bin

They are by default outputed in NONOS_SDK/bin. I guess they are default names given by the Esspressif's script. The first may be a kind of bootloader, the second is your application.
So I suppose you just need to compile your app :)

Agreed, One is like a boot loader and the other is your actual usercode..
The way I do it is a little different, I use the Blinky Example to output a
Blinky-0x00000.bin and a blinky-0x10000.bin
The 0x00000 is around 50.5KB and the 0x10000.bin is around 222.6KB (My code)
I burn to the coordinating addresses for non FOTA.
Let me know if you get it going.
