@pythoncoder :

Yes maybe, but i already checked all the joints with a binocular and it seems nice and regular.

Perhaps the following may help someone else. After using a laboratory power supply to power the ESP32 i had better results but the brownout detection did not totaly disappear (even with this power supply able to deliver 3A). And after a while it became more and more frequent. Finally i decided to us...

Ok, thanks.

I did not understood the warning as an issue, but the reboot yes
Especially because it never occurred before with the same ESP32 board, same cable and same computer.

I will retry with a laboratory power supply.

May i suggest little changes ? In machine_uart.c, line 218 switch (uart_num) { case UART_NUM_0: self->rx = UART_PIN_NO_CHANGE; // GPIO 3 self->tx = UART_PIN_NO_CHANGE; // GPIO 1 break; case UART_NUM_1: self->rx = 15; self->tx = 4; break; case UART_NUM_2: self->rx = 26; self->tx = 25; break; } To use...

@loboris,

Once again thanks for your precious help.

Dear All, I think i encountered an issue with UART : Trying UART1 _________________________________________________________ >>> from machine import UART >>> u = UART(1) >>> u.read() Guru Meditation Error of type LoadProhibited occurred on core 0.

@loboris:

ftp sever works fine now, thanks.

If that helps,

network.ftp.status()

return :

Dear Loboris, once again thanks for this awesome work and for your fast answers. I just pulled the new release, compile and flash an esp32-psram. The ftp server is present and i can connect to it (with filezilla), i can see the content of "/", but if i try to open "flash" (CWD flash) i have an error...
