Hi,

Please do NOT disable the hardware interrupt for a long time, it should NOT be longer than 50us.

And you can have a try with our latest ESP8266_NONOS_SDK_V1.5.3 which has fixed the "mac 674" problem.

If your problem is still unsolved, please feel free to let us know.

Thanks for your interest in ESP8266 !

I'm seeing very similar restart randomly (after 5-20 minutes) when using ESP8266 as RTP streaming receiver. In my application RTP packets are coming to ESP8266 at 50pkts/s rate then buffered in kind of jitter buffer and passed to I2S "fake PWM" as in popular mp3 decoder project. Sometimes log line is different: "mac 674", but usually it's the same - obscure "dev 1143". Source code I'm using and PC application I'm using for testing is available at http://tomeko.net/projects/rtp_pager/

Hi,

The problem can be reproduces by os_intr_lock() and os_intr_unlock()
But not holding the lock too long, and then in combination with lots of udp multicast packages.

I was driving a string of ws2812b led via bitbang. But after i switched to i2s implementation with dma all problems are gone.
Even increasing the packages more no problems found.

So for me its solved, i'm will keep my hands of the intr_lock in combination with wifi packages.

Thanks

The example code doesnt really help at all.
I'm using udp, and using the lwip stack.

But @Lieven

I think your piece of disassembled is the exception handler of the crash.

Somewhere inside your trace I saw a esf_pbuf_recycle.... That sound like a possible suspect.
Going to try some with custom lwip stack and other pbuf settings in lwip...

Thanks

Don't know if this helps. I got the same error dev 1143 using TCP connection/disconnect loop ( 2 sec interval )

dumping stack gives :

3FFFFD80:40104311 CODE wDev_ProcessFiq +0x2E5

3FFFFFF0:4000044C CODE UartDev +0x263C

This is not necessarily the exact trace. But disassembly shows :
40104302:fe9221 l32ra2, 40103d4c
40104305:fe9231 l32ra3, 40103d50

4010430b:ef9d01 l32ra0, 40100180 <_UserExceptionVector_1+0x24>
4010430e:0000c0 callx0a0
40104311:ffff06 j40104311

So a while(1); at 40104311

dev 1143 then wdt_reset udp server high rate packages (sdk 1.4)

2015-10-10T01:53:17+08:00

Hi All.

I'm getting this error for a while now, but never find anything online about it.

When im using the ESP (SDK 1.4), and let it connect to my mobile phone (as AP).
Then running an UDP client on my mobile, and UDP server on ESP.

And I'm sending at a very high rate (while true loop) udp packages from mobile to esp.
But after a while(3min) it first prints "dev 1143" then after 8 seconds wdt_reset occurs.

Why is "dev 1143" and who is printing it?
