Hi guys, Many attempts trying to get ethernet to work as DHCP server (along with wifi as DHCP server AP as well). I think it's kinda odd but it's our requirement. Doesn't seem to work. Ethernet always get assigned an IP. I used tcpip_adapter DHCP calls in event handlers to set it up. Code is as foll...

Hi guys, I wonder if we can access to the CPU architecture reference manual to esp32 dual core CPU similar to this http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.subset.architecture.reference/index.html for ARM As you know Xtensa is not popular like ARM where resources are abundant. If ...

Thanks for the fast reply. I checked the source code for start_cpu0 and start_cpu1, while it seems it's viable to just roll my own start_cpu1 but the fact that esp32's version of freertos has been heavily modded and the OS behaves differently depending on whether or not both cores are enabled , make...

BTW, I found that example apps have both cores enabled by default.
https://github.com/espressif/esp-idf-template only uses one core by default.

Thanks ESP_igrr. I found that in the default template app. "make menuconfig" will show up with unicore freertos already selected. So by default freertos will only run in single core mode. In my application, I have a timer ISR which will run at 30kHz. This means the core is interrupted 30,000 times p...

Nobody have answers for these questions or the answers are already scattered in the forum...?

Hi guys, I am in the middle of a project that does real time network communicate and at the same time the project also runs a timer interrupt at 30kHz. As you can see it is a very noisy ISR environment and latency is very important to me. I am trying to understand the behavior of all the tasks and f...

Thanks everyone for your timely help. That clears things up for us. I will get our engineers to modify our baords to use v1.0.

Again, thanks Expressif for prompt support!

Yea, I just can't seem to get hold of the v1.1 anywhere. Someone at Expressif please help!

Hi guys, While designing our next gen product, we found out that WROOM32 actually have two different trace antenna layout. This really creates problems for our PCB design. We will be using an extern antenna with our product and really need to make sure want have the test points at the right place. W...
