I soldered 2 - 8MB APS6404L-3SQR QSPI PSRAM chips to my Teensy 4.1. Since I have never soldered a SMD before I ran the memory test (teensy41_psram_memtest.ino from https://github.com/PaulStoffregen/teensy41_psram_memtest) and got:
Memory Usage on Teensy 4.1:
FLASH: code:28100, data:7064, headers:8864 free for files:8082436
RAM1: variables:7680, code:25432, padding:7336 free for local variables:483840
RAM2: variables:12384 free for malloc/new:511904
I don't understand these results both RAM1 and 2 are 524,288. I was expecting 67,108,864 or 8,388,608. Did I do the test wrong or install the memory wrong?
Thank you,
Vincent
