>> Have you tried combining "integrate into memory map" with ".bss in PSRAM"? Yes, but this for zero initialized data (.bss is created by the loader and set to 0), and my data is non-zero initialized (.data) that is part of the binary image. I looked for option to move the .data into PSRAM, but I c...

"Integrating into the memory map" means the IDF just makes the PSRAM accessible as RAM to the CPU. You can use it as "raw" memory by reading or writing data to its address range via pointers. The heap allocator is not made aware of this memory region Do you mean it makes it accessible at the HW (or...

I imagine that data won't change at runtime? If so, suggest making the array 'const' - that way, it stays in flash rather than be copied to psram.


Yes. this is correct and it WORKS!
And assuming psram read is faster than flash read, I can copy it to psram after program starts.

Thank you!

Thank you! (1) I "see" the heap using esp_get_minimum_free_heap_size call. We can also see the log during boot (below) it doesn't seem to add the PSRAM into available heap. (2) About " including 2MB of initialization data into the firmware binary", yes - this is my intent. I eventually would like to...

Hello, This may be a completely newbie question. (1) I'm trying to use the 8M PSRAM as "normal" memory, when I choose in IDF menuconfig to access the PSRAM via heap_caps_malloc -- I can see all 8M of it but if I integrate into the memory map I can only see about 300K -- why is that and how can it be...

I am running TF Micro, the PSRAM is used to allocate the tensor area, No code.
Can this interrupt be a page-fault? (assuming paging is enabled in Free-RTOS) ?

Hello,
I am getting an "access cache when cache is disabled" exception on ESP32-S3-EYE.
I am using the PSRAM and it may be related.
Did anyone see this before and knows how to fix the issue?
Thank you!

Thank you!
Still fails to allocate tensor memory - the model is likely too big for the available memory

>>> Have you enabled PSRAM in menuconfig? If not, you can only use the internal RAM, and that's probably too little. Thank you! and yes, I did, without it probably would not even load (it is a 4M image). That said menuconfig setup is somewhat complex and I may not have the optimal setting for maxima...

Hello, and thank you for reading my question. I hope I am at the right group to ask. I successfully compiled and loaded YOLOv5 nano using Tensor Flow lite Micro onto the ESP32-S3-EYE, using the hello_world template. The Binary segment size is as followed: text data bss dec hex filename 169,186 2,170...
