error: pll_cal exceeds 2ms!!!

[mash]

Hi,

I'm seeing this

Code: Select all

error: pll_cal exceeds 2ms!!!
error: pll_cal exceeds 2ms!!!


lines in UART when I power the module.
What does this error mean?
I haven't seen anyone else writing about this error.

I'm using ESP-WROOM-02 and SDK VERSION:1.5.3(aec24ac9)
This seems to be unrelated to software, because it happens when my user_init is like:

Code: Select all

void user_init(void) {
    uart_div_modify(0, UART_CLK_FREQ / 115200);
}

Hi,

Code: Select all

error: pll_cal exceeds 2ms!!!

This log means that operating RF during sleep mode, maybe you can disable the sleep mode and test it again.

Code: Select all

wifi_set_sleep_type(NONE_SLEEP_T);

Thanks for your interest in ESP8266 !

I have same problem
just after soldering the fresh ESP-12F on the board and upload the helloworld example of esp8266/Arduino , its throw
error: pll_cal exceeds 2ms!!!
in every couple of second without any crash and exception, instead no connection lunched whereas serial print shows its work and gain the ip address , I've checked couple of lib example as well and also put the wifi_set_sleep_type(NONE_SLEEP_T); inside setup but no success
is it possible the module had broken ?
