When not using SPI0 for cache/mmu/xip, such as running from ram, is SPI0 usable as a GP-SPI (fully equivalent to SPI1,2, or 3)? Can it talk to any spi device and send commands to it? IE is the SPI_USR bit in SPI_CMD_REG functional?

Re: Undocumented backdoor found in ESP32
I'm not going to accuse the obvious here, given that altruism is the most logical reason for providing so much (crippled) value for so little price, stressing to make everything but the most sensitive part of the logic open-source & verifiable.

Re: ESP32 External Oscillators Required?
Is it required to run at all, or required for wireless functionality only? I remember researching this long ago, but I've forgotten since then.

Does usb device support arbitrary (no/generic class) usb device?
I'm trying to create a simple "hello world" usb device, that doesn't follow any prespecified class type (not HID/MSC/etc), because I don't want any preexisting generic driver from my PC to pick it up. I'm trying to code a custom driver that kicks in based solely on VID:PID, which I have chosen ...

Slow Compilation Speed (<22% CPU Utilization)
Recently, compilation speed is not rising above 22% except for sporadic spikes to 50%. Does anyone have an idea what is causing this? This is the case irrespective if I compile in CLI or VSCode. Is anyone else experiencing this? I'm on Ubuntu 24.10 x64, Ryzen 5500U, 8GB RAM, Samsung Evo 970 Plus ...

Re: ESP32-S3 USB OTG - USB Hub support?
Why not just open it up as beta and let anyone/everyone test at their leisure? That's effectively how things are anyways with the rest of esp-idf, everybody heads to the issues section to report problems. I don't think it makes sense to require anyone/someone to proclaim themselves as official ...

Is redirecting stdout over JTAG possible?
Hi,
I've recently begun debugging esp32 through openocd/jtag. However, serial output is sent to UART0. Is it possible to send this data in-band over JTAG?
