ESP32 PSRAM support

[rudi ;-)]

Sorry for the short reply, but to be honest we haven't really looked t the D2WD/PSRAM combo that much yet... We will do this in the future, including determining which pins to use.

no problem so i know jeroen.
just in time think over small things that puzzles me
btw:

i know, there is on espressif / private a test case for D2
and the shematic is well knowed for using D2 well

Yes, I've been using one most days as a development device for over a month now. If using esptool.py on the command line or via IDF makefiles, ESP32-D2WD should be fully supported. ....
..
..
My ESP32-D2WD has revision 0 silicon. I don't know what chips you've received, I am guessing also revision 0

but not sure, how it looks and how it can deal with expansion ( pSRAM and so on )
so i ask, is this test case include a possible for later pSRAM testings or was this test case only for esptool and code test.
cause if here at desk things go on and successful i would write that you can test too ( if you can't cause there is no possible test case
it would be sade )

there are given nice test sockets for the QFN and i go on to do this on this way for first steps that we all flexible.
so it would be from interesst for the price for the test case, cause if pSRAM generall not possible on D2 then we know
and we do not build possibles on this test case here and save the money

so perhabs the question is greater, does we can use pSRAM on D2 generell.
if this just in time not knowed - no problem ( please feel free to make a short reply "not sure" then is ok )

with this test sockets

CYT009AriesTestSocket.jpg (50.12 KiB) Viewed 16105 times

or this qfn(32) -> qfn(48) socket on pcb

pcb_socket_qfn_custom.jpg (88.22 KiB) Viewed 16105 times

or others

i am flexible - with an pcb it is static.

thank you jeroen

perhabs if there is a new on this D2 theme and pSRAM, i bookmark this theme for append things in this thread.
would be nice, if you can append after new knowledge too here , thank you!

btw
just in time here at desk is starting test 128MiB flash(3.3) and 64MiB pSRAM(3.3) on D0WDQ6 and our testcase.
( MOQ later custom Wrover at espressif if success - )

nice weekend - enjoy it.

best wishes

@rudi
Can you tell mi with psram chip are you using?

@pmlody
just in time the esp-psram32
you can contact sales@espressif.com
( not sure is just in time available but talk to sales )

the second is lyonthek's
32, 64 and latest 128 - but this just in time pending ..cause

6).LY68L3200SL -32Mb 3.3V QPI pSRAM-Sample Jan./M/2018 and MP Feb./M/2018

hope for the parcel asap.
hope this helps

Any update on when psram branch will be merged into master or vice versa?

[ESP_Sprite]

If any, post 2.1.

[WiFive]

If any, post 2.1.

Ok so how to look at esp32 rev1 SPIRAM support in IDF from a product planning standpoint? Will it always be second class citizen in terms of IDF updates, separate branch? Do you suggest to consider waiting for "ESP-NEXT" chip for fixed SPIRAM and first class IDF support?

[ESP_Sprite]

Maybe my previous respons was a bit too short, as well as the 'if any' bit too easy to misread; my apologies. Let me correct that: Essentially no, the SPI-PSRAM support will be merged in the main ESP-IDF, but at the time I posted the branch here, the 2.1 release was too close to safely put it in there. We will try to merge it post-2.1, but we're not 100% sure of the timeframe; it'll probably get in there before 3.0 is released but it's not 100% certain.

Wrt hardware support: For the ESP32 dual-core version, while we do have ideas for the future, at the moment we aren't working on any metal revisions to fix the issues that need a compiler workaround. The ESP32 single-core revision however will have fixed SPI RAM support and should be able to run without compiler workarounds.

[WiFive]

OK thanks for clarifying. Any info on rev1+SPIRAM hardware and toolchain in unit testing and CI flow?

Would be nice to have firmware ready for production when wrover ships.

Would also be really nice to know when to expect S0WD, 8689, and the new chip.

please help to this never ending story now
we need now a detailed help - and the wrover shematic with HDK/BOM now for compare.

i have an espressif wrover modul with time stamp 502016 on the SOC and it is rev0
i wrote a simple firmware with testings and psram as spi ram for this and tested successfull.

FYI: i have the rev 1 too, and tested the same firmware successful, so i am sure, the fw ( code ) is ok

now we have a testmodul ( again soc rev 0 ) with lyonteks 32 MBit psram 1.8 and a 64 MBit flash.

the bootloader is booting and the first testings for test the flash is ok, it is the same code on firmware!
the SoC load the bootloader from SPI Flash well and start it
it wait now for user input for echo the inputs from the uart
we can communicate with it and to this "step" is all ok.
this let us know - the flash works - cause the soc can handle and read/save from and on the 64MBit flash
.. all ok to this step:

info: HDK
Bootstrap pin MTDI is pulled up to VDD33
SPI Flash share Data pins with PSRAM
PSRAM #CE is pulled up to VDD_SDIO and is connected to GPIO16
PSRAM SCK is connected to GPIO17

Q: why this exampe run on Wrover 32MBit_1.8/32MBit_1.8 modul ( SoC Rev 0 )
but not on the custom 64MBit_wide/32MBit_1.8 ( SoC Rev 0 )

Q: the 64MBit is wide flash ( 1.8 .. 3.6 V ) and works with 1.8 and 3.3 - is there a problem with 1.8 driven wide flash and combine 1.8 psram?

Q: we use Lyontek PSRAM, is there a magic key for psram ( ESP-PSRAM32 ) ID and if this not match the PSRAM is not supported?

Q: is there a hidden/not knowed detail on HDK that we not know? ( missing the edited wrover shematic file - can u post now ? )

Q: we need the HDK wrover shematic with BOM like the WROOM32 modul.

best wishes
rudi


edit1:
and sure:
here is the shematic we use :

flash and psram

now -
we need your shematic and info what we do wrong here.

edit2:
we work with cadence , eagle, kicad so there is no problem to import yours.

edit3:
FYI the name of PSRAM in Shematic is placeholder only ( it is named as 64 Mbit version )
we use 32MBit version on the Modul for the testings -

Rudi,
Can you use idf-monitor (make monitor) when capturing log output? That tool will decode backtraces printed by the panic handler into source code file names and line numbers, which will make it easier to figure something out from the logs.
