esp32 s3 has pwm error

[Ethanlaucan]

Dear Team：
I don't know if you've noticed that the PWM of the esp32 s3 firmware seems to be abnormal. I've currently tested the firmware released on March 28th. When setting GP2 and GP6 to send pulses, they can both run normally independently. However, when I use the new firmware released on June 17th, without modifying my code, I run the GP2 pulse first and then the GP6 pulse, but the chip still keeps sending the GP2 pulse and the GP6 pulse is not sent normally. I'm not sure which configuration has the problem. If you need me to provide more information, please let me know and I will assist in testing.

Please note that I am using ESP32 S3 N8R2 firmware which has disabled the default URAT

from machine import PWM,Pin
import time

def out(pwm,v=0,a=10,t=0):
pwm_io=[0,2,6,4,5]
pwm_set= PWM(Pin(pwm_io[pwm]))
v_io=[0,39,42,40,41]
pwm_pin=Pin(v_io[pwm],Pin.OUT,value=v)
pwm_set.duty_u16(32765)
pwm_set.freq(a)
time.sleep(t)
pwm_set.deinit()

out(1,1,800,2)
time.sleep(2)
out(1,0,800,2)
time.sleep(2)
out(2,1,800,2)#When using the June 17th firmware to execute this section, the stepper motor actually still performs the GP2 pulse.
time.sleep(2)
out(2,0,800,2)

This firmware uses ESP-IDF v5.4.2

The latest firmware I use is the August 8th version. I haven't tested subsequent versions yet.

I replaced this file with the previous 1.25 version and something magical happened, everything returned to normal, so I suspect that this file caused some PWM errors on the ESP32 S3
