Re: Increase monitor UART speed
You must have misunderstood. My apologies for not being clear. I did not say that disabling ROM bootloader output is not an option for me and neither is the garbage output a problem—other than that it looks like a mess. What I was trying to say, though, is that I wonder if there isn't a more elegant...

Re: Increase monitor UART speed
Thanks for the heads-up. Sounds a bit like a design flaw. Perhaps something to address in future chip revisions?

Re: Increase monitor UART speed
Hard-coded in the ROM, or hard-coded in the library code? I have no problem with modifying a component to make this work if that's what it takes.

Increase monitor UART speed
I'm trying to increase the UART speed for the monitor logging and for the most part I've been successful at it. However, there is a small first stage of the initial bootloader that still spits out only garbled symbols. It switches to proper text output from the second stage forward, but I could not ...

Re: Performance benchmark compared to Cortex M4 series
The biggest performance bottleneck of the ESP32 is its slow SPIRAM—80Mhz at the most. It turns any memory-intensive application into molasses. Even DMA transfers are completely bottlenecked by it. Further, what little of the 240MHz memory on-chip memory there is, is way too little for any serious ap...

Re: miniz library in ROM - usable for application development?
I know, this is an old thread but I just discovered it and it was super helpful! It made the migration from `ZLib` to `miniz` so easy and simple, and it worked with `libPNG` without a single hitch. The hardest part was actually finding the correct `miniz.c` version for modification, to match the one...

Re: Setting up Googletest with ESP-IDF
After days and days of trying, I gave up. I guess, Googletest is just not made for the ESP32, even though they have ESP32 and ESP8266 build paths in their code. Or perhaps, I'm just not cut out for this kind of CMake magic.

Setting up Googletest with ESP-IDF
I've been trying for the past days to set up a very basic example project to use Googletest but I have not had much luck. CMake and its clutter is just constantly getting in my way. I can't get it set up as a component and I can't get it set up as a lib either. Something's always going wrong. Has an...

Re: triggering WDT in OTA
Any side effects yet on that `OTA_WITH_SEQUENTIAL_WRITES` usage? I'm seeing WDT issues as well because I'm dealing with a pretty large OTA partition that takes over 6 seconds to erase. I've just tried `OTA_WITH_SEQUENTIAL_WRITES` for my case and it works fine, but it slows down the overall OTA time ...

Prevent reset when reconnecting monitor
I have two computers for my development—both of them Macs. On one of them, the device always resets when a monitor session is going on and I unplug and plug the USB back in. On the other computer, the device will not reset. Instead, it restores the previous link and continues the log output, which i...
