Re: ESP32-P4 chip availability ?
But when will they actually be available?

Re: ESP32-P4 chip availability ?
I assume the X means the 3.x version ?
However there doesn't appear to be availability anywhere. I need to know when I'll be able to order via JLCPCB or Digikey.

ESP32-P4 chip availability ?
Having previously ordered ESP32-P4 chips on PCBAs via JLCPCB (this was v1.3), I just noticed that the ESP32-P4 (P4NRW32 ) is now showing on LCSC as "not available now, discontinued", and there seems to be no stock at Digikey, Mouser etc.
Is this perhaps an issue with teh transition to v3.x silicon ...

Re: First ESP32-P4 board bringup - power problems
Yes, that was it !
I didn't realise that only the flash LDO is enabled initially, hence confusion over the other voltages.

Re: First ESP32-P4 board bringup - power problems
OK think I may have figured it out - I have V01..4 order reversed, so may have smoked the PSRAM - seeing if I can track-hack a new PCB to confirm.....

First ESP32-P4 board bringup - power problems
Hi - I'm trying to get my first ESP32-P4 board running. It is basically a copy of the Waveshare WIFI6-TOUCH-LCD-XC board (Schematic : https://files.waveshare.com/wiki/ESP32-P4-WIFI6-Touch-LCD-XC/ESP32-P4-WIFI6-Touch-LCD-XC-Schematic.pdf] ), with a few parts omitted (camera, audio, USB-Serial)

Re: ESP32-P4 MIPI double-buffering - can't work out how to swap buffers
Thanks - I saw a reference to Draw_Bitmap, but thought this was in the context of flushing a screen buffer to a SPI type display with its own memory.
Would be helpful if the DSI display documentation had mentioned this, as it's far from obvious!

Re: Struggling to figure out how to include IDF components
Thanks - I eventually managed to get it working by starting with the LCD demo, adding sdcard support, adding a kconfig file to add the sdcard-specific config items.

Vscode : compile warnings disappear from terminal window
New to VSCode, slowly getting there but can't figure this out...
During build, you see all the compiler warnings etc. scrolling up the terminal window, but when it completes successfully, the window gets cleared, and just shows the memory usage summary.
How do I either get back to the warnings ...

ESP32-P4 MIPI double-buffering - can't work out how to swap buffers
I'm working on a simple project which is basically loading and displaying images from an SD card to a MIPI LCD.
Not using LVGL, just throwing raw image data around.
Using IDF V5.5.4 ( as that was the example I started with used), Waveshare 3.4" round LCD board, with their BSP, configuration set ...
