Currently, I'm having a problem with running wifi examples on my board. When I flash the WiFiScan example, I get the following console output. Sometimes it will reboot and display the same messages a few times before it permanently hangs. Occasionally it will cause a kernel panic and crash my mac.
Code: Select all
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee

I am able to successfully run basic serial programs such as echoing serial console input, etc...
In searching the web before posting here, it was suggested to measure the logic levels of the bootstrapping pins...
GPIO 0: High
GPIO 2: Low
GPIO 4: High
GPIO 5: High
GPIO 12: Low
GPIO 15: High
At this point I’m really stumped. I would appreciate some help. Thank you.
