PSRAM problem while frame buffer init?

Postby salbdch » Fri Jan 15, 2021 12:24 pm

System keep rebooting while frame buffer init and here's log while.
I have no idea why free space on PSRAM shows abnomal values after allocating 960kBytes.

Case closed,

Was not exactly the PSRAM issue.
Please refer https://www.esp32.com/viewtopic.php?f=13&t=18950 if may someone interested.
