Looking forward to all the developments!

I'm having intermittent LAN8270 connectivity problems where ESP32 MAC -> LAN8720 PHY Fails.

When checking MDIO I see the read request, but no reply from LAN8720 PHY -> ESP32 MAC
When checking MDC, I see the time between each clock cycle to be 320ns = 3MHz.

The MDC Standard is minimum period 400ns ...

A nice thing about ESP32 is with Ethernet and Wifi, one chip and one program could do everything.

Adding C2 or C6 for Wifi is okay but the extra programming and juggling the programming header is a challenge, especially if each person needs to create their own protocol to go between P4 and C2 ...

Might be difficult due to the way the hardware has an address filter that only watches for a single address.

When using i2c_slave_read_buffer()

It it possible to determine if the master wants to "read" or "write" to me as the esp32 i2c slave target?

I figure the i2c address + write bit would allow me to figure out the intent, but it appears that write=true/false bit is not available via the esp-idf API ...

esp-idf v3.3

My custom ESP32 board uses a LAN8720.
Over the past year I had many of them fail, so I'm trying to determine the root cause (I already have 50Mhz clock start delay and TVS ESD protection).

In esp_err_t emac_reset(void)

It calls
REG_SET_BIT(EMAC_DMABUSMODE_REG, EMAC_SW_RST)

However ...

Solid reply. Thanks a bunch!

Hi,

I was looking at this:
https://github.com/espressif/esp-cryptoauthlib/tree/master/esp_cryptoauth_utility#using-atecc608a-with-esp32-wroom-32

I have a custom board with the ATECC608 but my I2C pins are on a different GPIO
esp_cryptoauth_utility/sample_bins/secure_cert_mfg_esp32.bin

Is it ...

I have a number of deployed devices with Secure Boot V1 & OTA Updates.

I want to make some new devices and read that ESP32-ECO3 uses Secure Boot V2 (RSA).

1) Does ESP32-ECO3 NOT support the old v1 AES signing?
2) Can I send the same OTA update binary to both devices? Seems it might be hard since ...

Hi thanks for the confirmation.
Yes if I have hit the flash speed limit then so be it!

Have a great day!
