Cheers!

Hi there! I'm experiencing strange behaviors on the VDD_SDIO voltage line: it is rather unstable, and among all the samples I have (and operating conditions) it varies from 1.7V up to 2.04V. Setup: Custom ESP32D0WDQ5 (revision 1) board with 4 MB Flash and 8MB PSRAM @ 1.8V. MTDI is pulled high. VDD_S...
