Re: I2C Slave address masking
Might be difficult due to the way the hardware has an address filter that only watches for a single address.

i2c slave read/write direction - how to determine?
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. Di...

emac_reset / EMAC_SW_RST not working
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 one o...

Mixed Secure Boot v1 & v2
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 the...

Re: Maximum Flashing Baud Rate
Hi thanks for the confirmation.
Yes if I have hit the flash speed limit then so be it!
Have a great day!

Maximum Flashing Baud Rate
I am having trouble getting flashing to work above an effective 825kbps. So with a CH340 I was able to set flashing baud to 921600 and it flashes effectively at 850kbps. Wrote 1388912 bytes (858612 compressed) at 0x00020000 in 13.8 seconds (effective 806.8 kbit/s)... And with a CP2102N I was able to...

Re: Raw ethernet packet
Wanted to bump this back up in case anyone could share anything they know about raw ethernet packet sending causing problems in a multi-task freertos environment.
