ESP32 PSRAM support

[rudi ;-)]

Good to hear you found the problem. So you have the Lyontek chip working as well now?

will get this lyontek wild horse this week,
btw please check jeroen ( FYI )

interesting, PSRAM & FLASH same QIO CLK time + frequency, why not share on 40MHz?
Because of SPI Read ID function only with 4 / 8 MHz ?

I think we can on custom mode the Read ID save and share the CLK in 40 MHz - would save a GPIO ( IO17 )

flash clk comes 2 clks earlier -
_ psram clk need a cycl after #CE goes high for terminated_

Hi

few weeks ago i got an email, that there is a guy, that have request samples
from a PSRAM manufacturer and if there comes samples, then he will share
if they send more as one

it was a long time cause one time the trader has shipped on wrong address and not to the guy.
so the manufacturer must send again to the trader for forwarding to the guy.

after this was done the guy send me again an email, that he get samples 3 peaces
and he will share to me one peaces ( how cool is that ? he got only 3 and he share to me from this one peaces - )

Today i got a parcel from switzerland and the guy did what he promissed.
i got today the long long waiting PSRAM in 3.3V and 64Mbit from Lyontek

it is the 64er L ( 3.3 ) version not S ( 1.8 ) version

so now, what i can do for the guy and you folks and me
i can test this on a Rev0 and Rev1 Silicon SoC ESP32.

First start was simple, does the 3.3V Version passes the ID Check.
This was done - and the ID Check passed successful

Then the next step was, to test this on a Rev1 and ... why not - i taked the Wrover-Kit where DOOM was run with 1.8V Flash and 1.8V ESP-PSRAM32 .

So i remove first the Case of wrover and saw, that the SoC was 112017 ( mmh ) and is still Rev1 ( mmh )
the next i remove the 1.8V ESP-PSRAM32 and the 1.8V Flash.
Then i solder the 3.3V PSRAM 64Mbit Version and a 3.3V Flash from a Wroom32

the MTDI ( IO12 ) was then pulled down ( GND )
cause there is 10K Ohm in the pulled up bootstrap line ( R9 )

checked then the fine 3.3V that comes from VDD_SDIO intern regulator

After this steps i flashed the DOOM Firmware and....


... it work's!

Stable, no crash? Try for 80mhz?

You have another wrover-kit to measure difference in power consumption?

You have another wrover-kit to measure difference in power consumption?

is the KIT/esp-idf up2date for 80 Mhz and psram combine?


#yes will do a patch and test#
but earliest after wednesday


edit: forget to answere the top question:
yes - i think it is stable - but have to test more with it.
btw 1.8V
32, 64 ( 128 comes in August )
now MP also 256Mbit

You can download the beta esp-idf and the toolchain from the usual spots (https://github.com/espressif/esp-idf and https://github.com/espressif/crosstool-NG) but be sure to switch to the psram-compatible branches. For esp-idf, the branch is called 'feature/psram_malloc', for the toolchain it is called 'xtensa-1.22.x-ext_ram_patch'. Note that there are no binaries available for the toolchain, you will need to build it from source. For the different OSses, this is documented here: Linux Mac (Sorry, no Windows support for this yet.). Note: In order to get the psram version, in the instructions at the 'git clone' command, replace 'xtensa-1.22.x' with 'xtensa-1.22.x-ext_ram_patch'. For esp-idf, just clone esp-idf as usual, then do 'git checkout feature/psram_malloc'.

after you have do 'git checkout feature/psram_malloc'
be sure you do this step then :
git submodul update --init

-> toolchain successful

Hi Rudi,
I got a piece of ESP32 WROVER KIT V3 board which had the ESP-WROVER with 4MB of psRAM.And I had git clone the feature/psram_malloc branch esf-idf code.The build failed when I open the ext PSRAM features.It seems need special xtensa-esp32-elf files .Since I use the Win7 64bit ,so I take the Msys2 as the IDE,which need xtensa-esp32-elf-XX.exe to build the firmware.I tried to make and build xtensa-1.22.x-ext_ram_patch version crosstool-ng but failed.I noticed you were using the win7 too.Could you please send me the xtensa-esp32-elf-XX.exe which could build the psram ESP32 code?Or Could you please tell me how to get the xtensa-esp32-elf-XX.exe which could build the psram ESP32 code?Thanx!

hi temp4eb

there is just in time officially no windows (*.exe) support for the feature/psram_malloc

you need to build the toolchain under linux and there you can then compile the code.

an other way is, you build the toolchain with posix and cygwin under windows
then you get the *.exe like you wrote.

see my attached log, this runs pretty fine - until last steps - debuger tools, then there is missing something
( have not look deeper just in time - but the next days i will try again )
perhabs ivan/jeroen can look into too - perhabs they see what is missing in the last steps.
its really the final step -- 99.99 prozent was done but i think there is a missing step ..
it was a fast try - but will try again slower next days

it is not 100 prozent finished -
so just in time - you must build the toolchain under linux.

next days i will try again
(I am unfortunately for 1 1/2 weeks (summer flu)
Can not be as I would like.)

if the cygwin build is 100 prozent successful then i will upload the toolchain -
and write the steps in windows for build it with cygwin ( posix )

hope this helps?!

Hi Rudi,
I got a piece of ESP32 WROVER KIT V3 board which had the ESP-WROVER with 4MB of psRAM.
And I had git clone the feature/psram_malloc branch esf-idf code.
The build failed when I open the ext PSRAM features.
It seems need special xtensa-esp32-elf files .
Since I use the Win7 64bit ,so I take the Msys2 as the IDE,which need xtensa-esp32-elf-XX.exe to build the firmware.
I tried to make and build xtensa-1.22.x-ext_ram_patch version crosstool-ng but failed.
I noticed you were using the win7 too.
Could you please send me the xtensa-esp32-elf-XX.exe which could build the psram ESP32 code?
Or Could you please tell me how to get the xtensa-esp32-elf-XX.exe which could build the psram ESP32 code?
Thanx!

so just in time - you must build the toolchain under linux.

next days i will try again
(I am unfortunately for 1 1/2 weeks (summer flu)
Can not be as I would like.)

if the cygwin build is 100 prozent successful then i will upload the toolchain -
and write the steps in windows for build it with cygwin ( posix )

hope this helps?!

best wishes
