Re: lwip http server, can't read from socket

Neil, we have an automated test suite which has two parts: ⋅  Compilation tests, build system tests, and a few unit tests which can run on the PC. Run for every commit, takes ~5 minutes to run. ⋅  Integration tests which involve real esp32 devices connected to a PC. Run for each...

How to debug ESP32 with JTAG / OpenOCD / GDB 1st part connect the hardware

This 1st part is mainly how to connect FTDI C232HM DDHSL-0 to ESP32 DevKitC (also called ESP32-CoreBoard V2) https://hydrabus.com/wp-content/uploads/2016/10/esp32-devkitc_with_FTDI_C232HM_DDHSL-0_JTAG_Debug.jpg For more details on JTAG /GDB /ESP32 OpenOCD see https://github.com/espressif/esp-idf/blo...

HydraBus Shield / Breakout board for ESP-WROOM-32 new version 1.1(rev1.0)

This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board. https://644db4de3505c40a0444-327723bce298e3ff5813fb42baeefbaa.ssl.cf1.rackcdn.com/55026ca8fe2840843aafa3db5696e0f5.png https://644db4de3505c...

Re: How to build a subset of the possible components in ESP-IDF?

Yes such feature will be great to speed up build time. It will be very interesting to also check other compiler option a bit like on ARM CortexMx with GCC 4.8 or more with LTO option (-flto) which heavily reduce final bin/elf size (elimination of unused functions) and also optimize speed. As for exa...

Re: Assembler language reference manual ...

1) A way to Count Leading Zeros of a 32bits unsigned integer Does such feature exist on ESP32 CPU ? Yes, using NSAU instruction. Compiler will generate it if you use GCC __builtin_clz() intrinsic. Thanks for the hint and the fact it support asm instruction for that I will test it later to check it ...

HydraESP32 with HydraBus (using ESP-WROOM-32 module)

I have just received an ESP32 DevC module (the 2nd) from Olimex today. I have desoldered ESP-WROOM-32 from it and then soldered it on HydraESP32 (see https://hydrabus.com/2016/08/10/hydrabus-v1-0-shield-breakout-board-for-esp-wroom-32-esp32/ for more details) Board available at OSHPark https://oshpa...

Re: ESP32 SRAM examples

Sorry, isn't going to happen. Aside from the fact that this revision only involves one changed metal layer which I'm not even sure contains any ROM data, we need the software to be compatible with rev1, which means that the workarounds for the current chip have to be in esp-idf anyway. Ah I was won...

Re: Assembler language reference manual ...

Not yet, sorry; we've requested it at Cadence, but they still have to get back to us. Be assured we post what we can as soon as we have their permission. You seem to need this manual ASAP. Can I ask what you want to make with it? Maybe there's a different way of solving your problem. My requirement...
