remember
i did change the code ( esp-idf ) in loboris repo

and build the micropython for esp32 like loboris description on github

now we run the first pSRAM test on Pico-D4

and
vola - no crash

test one - success
now testing pSRAM
...

..and here you are

Pico-D4-V4 ready for start

..did start the mod on a ESP32-PICO-D4-V4 -
...i try this time a custom technic
why not build layers by hand
i did use for the first time in this mod, let's see what happens..
i build an power supply layer first, and then wired the rest.

australia now 08:17 monday
good morning seon
here in germany now is 10:17 PM ( sunday )
...
let's start

edit: i just in time play with loboris microPython and Pico-D4 want solder single psram on week start at a pico d4 play modul. let see whats happend and how the time stands for it. Hey rudi... um, I think I understand what you are saying... You are wanting to solder a PSRAM to a PICO-D4 and play wi...

On PICO-KIT I am using CS - GPIO9 CLK - GPIO10 SIO[0] - GPIO8 SIO[1] - GPIO17 SIO[2] - GPIO7 SIO[3] - GPIO11 it looks good btw chao's ( electrodragon ) IPUS PSRAM must (should) work. E (1790) spiram: First Error after 111806 good writes E (1839) spiram: SPI SRAM memory test fail. E (1839) spiram: W...

I don't quite understand what you mean by " next step is psram.c ". psRAM is fully supported in this MicroPython port and works very well. sry for confuse i mean the pico-d4-v4 pico-d4-v4.1 psram theme on PicoD4 i played just in time with the spiram_psram.c and Kconfig a little likewise spiram_psra...

@Boris txs!.jpg i must say - you did an amazing work Boris! i did think very complex ( set IDF Path, set toolchain, used as component and and and ..) and want install it on a complex other way and run on win 7/64 in a circle with waste time. :roll: you did a great BUILD.sh and with this one all was ...
