Re: What would you like to see in The Next Chip?

An S3 with ETHERNET MAC.


No need for PHY, just the ETH MAC.
SPI connectivity solution to a eg SPI to ETH module has proved very poor, eg WT32-ETH01 (a plain ESP32 chip) outperforms the ESP32S3/W5500 hands down having 2 or 3 times the speed.
It is a bummer that the top of the line S3 has no ETH MAC.

Re: ESP32-S3 JTAG debugging using Espressif IDE

As per default configuration, ESP32S3 comes with NOT being able to use the JTAG pins.
You need to set a efuse in order to enable JTAG pins 39 to 42.

Re: ESP32S3 maximum SPI slave transaction size ?

Just to answer my own question, I tried to use esp32's forum search but it is not working for me at least, with plain google search though found the answer. It seems that my question is already answered here https://www.esp32.com/viewtopic.php?t=2244 after testing this, SPI transfer size can be set ...

ESP32S3 maximum SPI slave transaction size ?

Hi, Working with ESP32-S3-DevKitC-1 as SPI slave. Need to have large size transfers, > 4096 or up to 32768 bytes. Tried the ESP-IDF SPI slave example modified to large transfer sizes but it worked only for up to 4092 bytes per transaction. What is the maximum SPI slave transaction size with ESP32S3 ...

Re: Resample examples not working

Hi, Changed the sdkconfig setting as instructed, now the memory issue is ok though a new issue came up regarding channels. to remind you, this is the =untouched= pipeline_resample example, it is verbatim without any change from me, just as it comes from esp-adf github repository. Specifically this i...

Is ESP-ADF still supported ?

Hi, Seen responses in esp-adf forum and in github issues up to early September, from then on for the last 2 to three weeks there is a practical stop in github issue answers, in commits and to answers in forum. To be honest, esp-adf is very cumbersome to say the least in its usage with lots of intric...

Re: ESP32-S3-WROOM-1 N8/N8R2/N8R8 memory

Hi @ESP_Sprite, Thanks for making this clear. It needed for me to do some reading regarding the memory scheme of ESP32 CPU and now I think I got a grasp more or less of the SRAM0/1/2, D/IRAM, flash and PseudoStaticRAM. Did successfully the required calloc() that I was trying to do earlier (and faile...

Re: ESP32-S3-WROOM-1 N8/N8R2/N8R8 memory

Hi @ESP_Sprite, thanks for answering. Got a few blanks though regarding the details of the ESP32S3 part numbers and of RAM usage in the modules. What ESP32S3 part numbers are actually inside the modules ESP32-S3-WROOM-1-N8 ESP32-S3-WROOM-1-N8R2 ESP32-S3-WROOM-1-N8R8 as I did not found this specific ...
