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.

Raw ethernet packet

I noticed that if I carelessly use esp_eth_tx() to send raw packets that it tends to kill my MQTT sessions. Probably something nasty going on. I see there's some LWIP stuff, and an ethernet_output() call that a lot of other stuff uses.. seems to be a more systematic way to queue/send... but didn't q...

Re: Transparent FS Encryption "Rewrite" Data Clarification

Thanks Wifive!

Do you happen to know, does the spiflash for fatfs refer to the onboard SPI flash (I assume a particular partition) within the WROOM32 module? Or does it refer ONLY to offboard spiflash (just like offboard sdcard)?

Transparent FS Encryption "Rewrite" Data Clarification

I understand that flash allows bits to go from 1->0, then we can reset a 4k page back all at once from 0->1 Yet esp-idf allows just 32bit writes to an encrypted partition. https://docs.espressif.com/projects/esp-idf/en/latest/security/flash-encryption.html#setting-flash-crypt-config > AES-256 operat...
