RTOS_SDK last commit ShowCritical

[gustavomassa]

Hello,

The RTOS_SDK last commit e1e17a1to (wujiangang sync: from 61124bba)
1. driver:
1). Fix hw_timer issue, #96;
2). Fix SPI output data error;
3). Fix SPI read data bug;
4). Fix driver lib compile issue;
5). Fix uart flow control issue;

2. lwip:
1). Enable lwip ETHARP_TRUS_IP_MAC;
2). Modify dhcp/dhcps timer from 60 seconds to 1 second;

3. WiFi:
1). Support CSA;

is unstable, it is running on ShowCritical: 0 trap during the wifi station/ap scan.
These are the files that are generating the problem:

UPDATE: The problem is not related to the lwip lib, I updated the dhcpserver files and lwip.a and the wifi is working fine.
The problem is related to libmain, lib80211 and libpp

Please investigate.

I have the same problem:

Before update:
entry station mode to connect server
bcn 0
del if1
mode : sta(5c:aa:dd:00:12:19)

scandone
state: 0 -> 2 (b0)
Ustate: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 2
pm open phy_2,type:2 0 0
cnt

After update:
mode : sta(5c:aa:dd:00:12:19) + softAP(5c:aa:dd:00:12:19)
add if0
dhcp server start:(ip:192.168.4.1,mask:255.255.255.0,gw:192.168.4.1)
add if1
bcn 100

entry station mode to connect server
bcn 0
del if1
mode : sta(5c:aa:dd:00:12:19)
scandone
ShowCritical:0

Hi,

Can you provide the test code for debugging?

Thanks for your interest in ESP8266!

OBS: The network that ESP8266 STATION MODE is going to connect must exist to reproduce the error.
OBS2: This example works fine using the old version of libmain, libpp and lib80211.

Another question, can you folks please improve the port.c file from RTOS_SDK/third_party/freertos, that file is really a mess, there are a lot of commented code inside it... Also please update the ShowCritical() function to use os_printf instead of ets_printf, and print the entire stack, so we can see where the problem is hapenning...

Code: Select all

void ShowCritical(void)
{
    ets_printf("ShowCritical:%d\n",uxCriticalNesting);
    ets_delay_us(50000);
}

Thanks

One more vote for this:

Please improve the port.c file from RTOS_SDK/third_party/freertos
Update the ShowCritical() function to use os_printf instead of ets_printf, and print the entire stack

And please, can you remove the "pwm version nnnn" from pwm library.

Thanks.

After the lastest commit the "ShowCritical" bug that was occurring during the wifi scan was partially fixed, sometimes it is still happening.

Code: Select all

231,694 (gdb)
231,713 @"(user_init) 124189383 - SDK vers"
231,717 @"ion: 1.5.0-dev(1aafc07)\n"
231,723 @"(user_init) 124190051 - Free hea"
231,727 @"p size: 38920\n"
231,732 @"mode : sta(5c:cf:7f:0f:08:eb)\n"
231,734 @"add if0\n"
235,310 @"ShowCritical:0\n"

Also sometimes while debugging the code using gdbstub, I face the ShowCritical: 0 and ShowCritical: 1 messages, something related to the freeRTOS scheduler, probably during the context switch/vPortMalloc/vPortEnterCritical/vPortExitCritical.
Please update the port.c file with the ShowCritical function to include the entire stack on the print.

Hi,

We are using ESP8266 RTOS SDK 1.5.0 in which we have faced ShowCritical:1 issue and after that Board restarted due to Watchdog Reset Reason.

So, Here We are using some spi_flash_write APIs in which we have put xTaskEnterCritical and xTaskExitCritical while writing any data into ESP8266 SPI Flash Memory.

So, how to recover that issue if anyone knows about that?
