Re: FreeRTOS SDK : UART ISR compile error

Howdy Andrew,
I see that there is a new release of the RTOS SDK ... maybe have a try with that and see if there are any changes?

Re: [SOLVED]New router does not work with RTOS sdk

Looking at your code I am confused by the task implementations. It seems you are performing:

Code: Select all

while(1) {
}


tight loops. Surely if one of those tasks gets control it will never release it since I understand that the FreeRTOS is not preemptive ...?

Re: issue on WDT RESET程序调试时不断出现重启

A watchdog timer reset exception occurs when your own application code has control and does not return control back to the ESP8266 environment in a timely manner. Examine your code and see if you have any loops or blocks that may be preventing return from your callback functions.

I'm afraid I'm not understanding the question. Would you be able to explain it in more detail?

Looping in a simple task

I am practicing with the latest RTOS SDK. I have created an application which creates a task and in that task I display some data and then sleep and then loop some more repeating the display/sleep pair. When I run the application, it displays between 8-20 iterations from the loop and then WDT resets...

Missing definition of uart_div_modify in RTOS SDK

I have started to explore the RTOS SDK and was trying to compile "uart.c". I find that I can't compile it because we can't find a prototype for "uart_div_modify". I searched my downloaded copy of the Github repository and there was no definition of that function. Can I ask that y...

Re: HSPI Documentation confusion ...

Howdy, Was reading this post again ... can you check the settings. You say: MTDO > CS MTCK > MOSI MTDI > MISO MTMS > CLK while I say they might be: MTCK -> SCLK MTMS -> CS MTDO -> MOSI MTDI -> MISO It seems we disagree on MTDO, MTCK, MTMS ... the only one we agree on is MTDI ...

Re: RTOS_SDK V1.3 do not fit my code any more

Howdy, have you tried modifying the eagle.app.v6.ld linker control configuration file and lowering the start location of irom0_0_seg and increasing its length. The default on an Espressif SDK system is only 245,000 bytes out of the possible 512,000. How much flash does your ESP8266 actually have? Wh...

Re: RTOS_SDK V1.3 do not fit my code any more

How much flash memory do you have on your ESP8266 board? Assuming your either have 512K or else are configured to use 512K, you may also be configured to use an "Over the air" (OTA) mode of linking. In OTA, the 512K gets split into two units of 256K. One for the program already loaded and ...
