ESP32 PSRAM support

[rudi ;-)]

hi folks
the unofficially windows future/psram_malloc toolchain is ready - on weekend i will upload it.
successful tested in
-> eclipse (see here the video sequenz )
-> npp
-> code::block
-> DevC++
-> Windows Shell

Hi Rudi,
Thanx for your reply!Looking forward to your exe files when you are available....

pack it here
the thread becomes until weekend a finnish in all details.
hope this helps

how you get on in cygwin64?
i suggest you take cygwin32, same like msys32 is simpley mingw32
and you are ready for old backed winXP for few reason too

best wishes

Hi Rudi,
Thanx for you files and explain!I'm still working on cygwin64 to build the exe files according to your steps.I download the exe files and replace the original xtensa-esp32-elf dir in msys2 with them.And build failed:

it seems these files which were built in Cygwin could not be used in Msys2?Since we are familier with Msys2 IDE for ESP32 development,I still want to get the Msys2 version xtensa-esp32-elf-gcc for ESP32 PSRAM modules.I will post a request for official help.Thanx!

this is a very bad idea

look in the c:\msys32
folder, there is mingw32
no cygwin

msys2 = mingw32 with mix of cygwin tools on mingw32 base

cygwin = pure posix

for this reason you see 2 versions of cygwin1.dll in the bin folder
for reason for more time postings i will finnish my thread until weekend
then you will read all details - i thinked you know what you do with the cygwin exe

this step was not the ideal doing.

all infos why this so is stand in the log -

it seems these files which were built in Cygwin could not be used in Msys2?

on this art you try - no way -
you try to mix now mingw32 with cygwin canadian cross build and possix cygwin

Msys32 original Build was done in a Linux PC 64 bit, for the i686 windows 32 bit :

Code: Select all

[EXTRA]  Dumping internal crosstool-NG configuration
[EXTRA]    Building a toolchain for:
[EXTRA]      build  = x86_64-pc-linux-gnu
[EXTRA]      host   = i686-pc-mingw32
[EXTRA]      target = xtensa-esp32-elf

mingw32 != cygwin
mingw32 = c:\ c:/
cygwin = /cygdrive/c/
cygwin32 != cygwin64

Since we are familier with Msys2 IDE for ESP32 development,I still want to get the Msys2 version xtensa-esp32-elf-gcc for ESP32 PSRAM modules.I will post a request for official help.Thanx!

the official "mingw32" ? "cygwin32" toolchain will come on the master later time, ( which i think mingw32 )
psram comes then merged into later i think -

i am not sure you read the postings and warnings from the postings in detail?
i think it is better you wait for the officially -
Msys2 contains only the make tools like GNU make, python support, serial and so on
the same is possible with cygwin, and there is the reoson why you get cygheap error,
you try to combine difference versions...
a cygwin toolchain in a mingw32 make tool environment
( is possible - but you need to follow my unofficial thread cause i will only one time post the describe )

if you want use the unofficially toolchain exe ( cygwin build )
then you must build this by self with the same way for an

host = i686-pc-mingw32

if you want use your Msys2 mingw32 build for a toolchain build
further then you need the sourcen of all dll you have in msys-*.dll
...
and so on and on
...
not sure why we note this -
nobody read this

RTFM*

Hi Rudi,

fine!

now go to your build folder
not sure where your home is
...crosstool-NG/builds/xtensa-esp32-elf/bin
and check the version of xtensa-esp32-elf-gcc-5.2.0 with -v
and post it.

thank you

Code: Select all

-build=x86_64-build_unknown-cygwin --host=x86_64-build_unknown-cygwin --target=xtensa-esp32-elf

you build on x86_64Bit cygwin unknown machine
the toolchain for using it on the host on x86_64Bit cygwin unknown machine
and you build FW for the target xtensa-esp32-elf

have you seen the version of my posted cygwin32 toolchain?
it is for 32bit ( will run on win10/32bit too )

Code: Select all

 --build=i686-build_pc-cygwin --host=i686-build_pc-cygwin --target=xtensa-esp32-elf

cause this is an unofficially it becomes named toolchain from who is compiled, when and becomes also a bugurl
where you send bug message

The heap allocator needs a few bytes for internal housekeeping, yes.

@jeroen
very well future!
honest!
very well!

i just discover the really nice difference from allocating and not allocating by ptr addr code ( full > 32Mbit.. )
and i must say - you did a very nice work on this pSRAM diver. @costaud you too
this is realy your theme park - very well!

i only play with this theme for the last weeks
and have gained a lot of insight and makes a huge fun.
i hope you got an extra bonus for this great achievement!
your future is with me at the uppermost place.
too bad that this topic has started so stupid
a lot of strife could have been avoided.
( i like you )

i just wanted to tell you: you did a great job for us all!

i try to put another(further) jewel on your crown,
i do not know if it will succeed, but I will let you know
that I am currently trying crazzy things just in time, cause got engineering pSRAM confident samples.

i think this can go further way as "reference thing" to use pSRAM in any of µControllers who support "SPI RAM"
and i will named it here "jro-N" tec and get in code the prefix "jro-N" in all functions.

you did nice work!
