[TTGO T7 / Mini32] Unable to access SPI Flash

Post by lukesky333 » Tue Nov 24, 2020 10:35 am

Hi,

I'm trying to access the SPI Flash on my TTGO v7 1.3 (Mini32). Is there an example how to do it?

Code: Select all

I (617) psram: This chip is ESP32-D0WD                  
E (617) spiram: SPI RAM enabled but initialization failed. Bailing out.
I (617) cpu_start: Failed to init external RAM; continuing without it.
I (625) cpu_start: Pro cpu up.
I (628) cpu_start: Application information:

E (10) spiram: SPI RAM not initialized
MicroPython v1.13 on 2020-09-02; ESP32 module (spiram) with ESP32
Type "help()" for more information.
I tried to google it but I haven't found anything helpful...

Thanks for all hints!!!

PS: I'm using esp32spiram-idf4-20200902-v1.13.bin - hope it is the correct?!
