Hello, I am using ESP32S3 module, ESP32-S3-DevKitC-1. Though in module there is PSRAM but when I try to configure it through the menuconfig it does does work. So may be in SDK PSRAM support is still not available. May I know some
when this PSRAM support for ESP32S3 will be available in SDK? Thanks.
Hi,
firstly,
ESP32-S3-DevKitC-1-N8 which was for sale on Digikey (last weeks) etc is the one without PSRAM so you have no PSRAM on the Kit.
it comes to market soon ..
If you have your PSRAM DevKitC from espressif sales app:
( ESP32-S3-N8
R8 or the ESP32-S3-N16
R8 or or N4
R8 or N4
R2 orN8
R2 or N16
R2 )
see here: WROOM Table helps little for orientation for what N#R# stands for:
then your Kit is ready-
or you did
append PSRAM byself on a basicly ESP32-S3-DevKitC-1-N8 so check you did it right,
then
checkout you have the right SDK installed, for the ESP32S3 ( not ESP32S3beta ) you need the latest ( 4.4..) IDF and tools
for your Hello_World you set then with
idf.py set-target esp32s3 your Hello_world example ready for the esp32-s3,
then you call the menuconfig by
idf.py menuconfig
in the menuconfig you should now see used
toolchain for the esp32-s3 ( not esp32-s3-beta )
then you go to the esp32-s3 menuitem and
activate the
support for
psram
depended on your used PSRAM type, manufacturer, size you set the right paramaters for the PSRAM (Octal, Spi, CLK rate ..auto )
check the uses pins for
clk and
cs# ( should be used for theDevKit like it is set
by default )
and you are ready.
hope this helps with this short answere.
if any, feel
free to reply with questions and we talk
step by step.
best wishes
