Enabling PSRAM crashes over printf

[davidacol]

Good day everyone, I'm using the ESP32 WROVER E to build a project for my embedded software university course. I initially built my project using the integrated flash memory but It's kind of essential for my project to use PSRAM since the size of the internal flash is insufficient. After enabling PSRAM inside menuconfig and doing the necessary changes (mainly moving from malloc to heap_caps_malloc) the code keeps crashing while executing elementary functions (in the following case: a printf)

Code: Select all

I (1267) esp_psram: Adding pool of 4096K of PSRAM memory to heap allocator
I (1275) spi_flash: detected chip: generic
I (1277) spi_flash: flash io: dio
W (1280) spi_flash: Detected size(4096k) larger than the size in the binary image header(2048k). Using the size in the binary image header.
I (1293) main_task: Started on CPU0
I (1303) esp_psram: Reserving pool of 32K of internal memory for DMA/internal allocations
I (1303) main_task: Calling app_main()
=== PRINTF TEST 1 ===
Free heap: 4404088
Free PSRAM: 244095
I (1313) sdspi_transaction: cmd=52, R1 response: command not supported
I (1353) sdspi_transaction: cmd=5, R1 response: command not supported

(the NEW_SA~1 line isn't gargabe, it's the contents of an SD card)

The code works fully as expected if you turn off PSRAM. I'm at my witt's end, but if you need any additional context or details i'll be happy to help. Thanks in advance!
