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

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...

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.

I have IGMP working with lwip RTOS SDK 1.4.2. void ICACHE_FLASH_ATTR handle_udp_join_group(void) { printf("handle_udp_join_group\n"); struct ip_addr ipgroup; struct ip_info local_ip; const WIFI_MODE mode = wifi_get_opmode(); if (mode & STATION_MODE) { wifi_get_ip_info(STATION_IF, &...

I have the following working code with RTOS SDK 1.4.2 : void ICACHE_FLASH_ATTR handle_udp_join_group(void) { printf("handle_udp_join_group\n"); struct ip_addr ipgroup; struct ip_info local_ip; const WIFI_MODE mode = wifi_get_opmode(); if (mode & STATION_MODE) { wifi_get_ip_info(STATION...

Hi Gustavo, It is possible. I have the following working code with RTOS SDK 1.4.2 : void ICACHE_FLASH_ATTR handle_udp_join_group(void) { printf("handle_udp_join_group\n"); struct ip_addr ipgroup; struct ip_info local_ip; const WIFI_MODE mode = wifi_get_opmode(); if (mode & STATION_MODE...

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...

We are working on SDIO SPI mode now, it will be released soon.

Thanks for your interest in ESP8266 !

Any news on the availability ?

Thanks, Arjan

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 ...

Hi Iolaso ,

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