Hehe no,

I'm using esp32s3 wroom1 n16r8 module so...

But i thought it was possible to change the three pins 36 37 38 .

I'm a bit mixing all the informations in my head i will delete the post because you are right i was mixing informations in my head

Hi I try to cnifgure for my board the external psram 8MB of my wrrom n16r8 but even if the ram if detected, there is a config issue: As i have 8MB here, i selected Octal Mode, and it select by default pin30 and 26 for sck and cs, pin that are normally used on my pcb, but i removed the component to b...

Thanks a lot for your rapplu, i understand much more what's happen. It was not really clear till now. I confirm what you said. In addition to bluedroid ( i need may be to switch to nimble as i only use ble) and wifi soft ap, i have 50% of the internal ram used by my gui LVGL for graphic display( a l...

So all the ble , wifi, lvgl will never go into the 8MB ram ? The 8MB or 2MB ram are external memory ?

Hi, Wroom ESP32S3 N16R8 I'm meeting issue with memory management when i call init_ble_gattc_gatts, a function whitch create and start bleudroid client and server. It is call just after sd card mount function that mount properly : void Task_ble(void){ ESP_LOGI(TAG, "** In task BLE **"); ESP_LOGI(TAG,...

Ok thanks, Is the rc filter and enable pin internally switch off/on when there is a reset via vs code ? Or is it just when we supply the board ? I also wonder why my ESP-IDF Size command do not change the RAM size and i'm still in overflow whereas I change the device from 2MB to 8MB of ram ( N16R2 t...

Before to add the rc circuit to EN pin, i tried to force boot gpio0 pin to 3.3v, and it seems to pass. It is not in download waiting state now, but the program seems to not fully start : PS C:\Users\Flo\esp\project_test\lvgl3\lvgl3> & set IDF_PATH='C:\Users\Flo\esp\esp-idf' PS C:\Users\Flo\esp\proje...

here the schematics.

I will try to add the rc circuit to be sure it deson't come from this.

Hi, Thanks for the reply. The boot pin is tied to 3.3 through a 100kohm resistor. The EN is directly connected to 3.3v. I have seen in the datasheet after ordering the pcb that it is advised to use a rc cicuit on EN pin with 10kohm and 1uF but I dont know if it is is the cause. Other straping pin le...

Hi, After reaching the limit of ram capacity of my esp32-s3 N16R2 , i meet issue by being not able to boot anymore: The program is flashed properly, but after reset, i have this console: --- WARNING: GDB cannot open serial ports accessed as COMx --- Using \\.\COM7 instead... --- idf_monitor on \\.\C...
