Did you find a solution to make the new() operator allocate from the SPI RAM ? A few. You can checkout our code at: https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3 In particular: https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/blob/master/vehicle/OVMS.V3/main/ovms....

N.B. This link seems to work (from the commit message):

I'm trying to download the toolchain for 3.3.2 release (with the PSRAM corruption bug fix), for OSX, but the download link is failing. Site I am using is here: https://docs.espressif.com/projects/esp-idf/en/release-v3.3/get-started/macos-setup.html Download link is: https://dl.espressif.com/dl/xtens...

Hi, I am SPIFFS library to store the data received from bluetooth into flash.At the same time two timer interrupts are working. But I am facing an issue , both timer interrupts and SPIFFS crash the ESP32 and shows an error 'Guru Meditation Error: Core 1 panic'ed (Cache disabled but cached memory re...

I'm hoping I can find time to finally finish this in the next few weeks.

Thanks for the update. Very helpful.

If/when you get a toolchain, please let us know. This is impacting us quite badly.

We're coming into 4 months after this bug was reported, but no movement on the GitHub issue.

This is a fundamental random memory corruption fault that is causing all sorts of issues. Can we get a resolution, or at least an update as to what is going on?

We wasted about a year with external flash. It works ok on WROOM32 (in DIO mode), but just too much trouble on WROVER32 (due to no spare 1.8v GPIO for CS, 1.8v not exposed externally, level shifting, hard-coded firmware not supporting it, etc). My recommendation is to use modules with 16MB flash alr...

espefuse output is showing: Identity fuses: MAC MAC Address = 30:ae:a4:53:dc:b1 (CRC b2 invalid - calculated 0x3d) R/W and that causes a fatal error on boot: I (659) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE E (669) system_api: Base MAC address from BL...

What is the expected output of this PPPOS? I have interfaced GSM module(from simcom) with ESP32 and ESP32 is in WIFI AP mode. I need internet access to devices which are connected to ESP. A wifi hotspot? What you would need is: A router for messages going between the two interfaces. To do Source NA...

Scan can be done in AP+STA mode, but it will interrupt the AP activity while scan is in progress. AP+STA in general works well. You can even leave the STA side idle (just used for scanning, etc) while the AP is running. Only issue is that you can't leave the AP idle (if unconfigured, it just starts ...
