Re: No documentation on spi_flash_get_id

The flash ID is a 24 bit number.

First 8-bits are representing the manufacturer -> https://github.com/jhcloos/flashrom/blo ... ashchips.h
The second 8-bits gives the type.
And the third 8-bits gives the capacity -> 2^capacity Mbits

Raspberry Pi ArtNet Wifi -> DMX out / Pixel controller

I am using the ESP8266 together with Raspberry Pi Zero (or A+, the Model 2's are already a little bit too powerful ;)) The ESP8266 is responsible for the Wifi / UDP stack. The technical interface is as follows : /* * RPi ESP8266 * * 11 GPIO17 -- -> GPIO5 * 13 GPIO27 <- -- GPIO4 * * 15 GPIO22 <- DATA...

An application note on the printed runtime messages by the SDK

Hi,

Is there an application note or WiKi page available for the printed messages by the SDK?

I am mostly interested in the 'state' message description.

Re: c_types.h #define ICACHE_FLASH_ATTR Hence, the code is not placed in .irom.text anymore.

Hi Pratik, Thank you for the reply. Much appreciated. I have replaced the simple "%s\n" printf's with my own written int __attribute__((section(".irom0.text"))) uart0_puts(const char *s) { char c; int i = 0;; while ((c = *s++) != (char) 0) { i++; uart0_putc(c); } return i; } This...

c_types.h #define ICACHE_FLASH_ATTR Hence, the code is not placed in .irom.text anymore.

With ESP8266_RTOS_SDK 1.4.2 , the #define ICACHE_FLASH_ATTR is empty. Hence, the code is not placed in .irom.text anymore. According to the manual "ESP8266 RTOS SDK Programming Guide Version 1.4.0" -> "Since ESP8266_RTOS_SDK_v1.2.0, functions are stored in CACHE area by default, need ...

Re: 【Feedback】RTOS sdk: FOTA Upgrade

Hi Iolaso ,

Are you able to link your OTA application? Which library did you use for system_upgrade_start()?
