SD_MMC works but after a random time fails until I power it off

Hardware

• ESP32_Wroover B
• uSD 32GB
• LAN8720
• IDE Arduino
• Upload Speed 921600
• Flash 80Mhz

Description
I follow the instructions of the connection on the next link.. https://github.com/espressif/esp-idf/tree/master/examples/storage/sd_card#note-about-gpio12

• D2 - GPIO 12 (PULL_UP by code => pinMode(12, INPUT_PULLUP)
• D3 - GPIO 13 (10Kh pull-up)
• CMD -GPIO 15 (10Kh pull-up)
• VSS -GND
• VDD -3.3V
• CLK -GPIO 14 (10Kh pull-up)
• VSS -GND
• D0 -GPIO2 (10Kh pull-up)
• D1 -GPIO4 (10Kh pull-up)

When I try just the SD_MMC it works great without problem, I tasted 7 days continuously, but when I add Ethernet (LAN8720) after 2 or 3 days sometimes after 1 or 2 hours the SD stops working, I have to restart the ESP by powering off other ways such as restarting by code doesn’t initialize the SD and it fails from the beginning .

I try also with SPI_SD protocol and happens more less the same, after some days the SD fails.

Steps to reproduce.
Use SD_MMC with Ethernet Connection, append some data on a file and wait until it fails

The LAN8720 connection is the follow...

I got the same issue, how can you fix ?

[hepa94meca]

The problem was solved, it was a power supply issue, my current was not enough.
