not public yet - but there is one.
in the meanwhile few info is available in part of code. furher parts : S2part S3part further ( there are many hints in the code)
yeap - this modul not using spi octal bus - i have few OPI samples (APMemory, ISSI, .. ) here ( Flash and PSRAM ) in 200 Mbps and 133 Mbps Datarate version ( 1.8V / 3.3 V ) - i think i will use in final design the 1.8V version ( flash and psram ) perhabs 256Mb flash and 256Mb psram in the base, and 1Gb in a test, cause they are fast enough ...
**easter egg in the IDF**
note 1: MX25UM25645G Octa Flash
ISSI PSRAM 256Mb ( Mouser: 870-6WVOM38DAL200BLI Manufacturer: IS66WVO32M8DALL-200BLI )
APmemory PSRAM 64Mb further
i will update this post on weekend with a "dark pixeld" OPI Version Modul so you can not traceroute the traces on modul
but by code - i think now i will be killed by you then if i did this let me think over few days how i can do it.
