I noticed today Arduino IDE is only giving me half of my 1MB of RAM on my Arduino Giga, is that normal? Thanks!
The GIGA R1 WiFi supplements the 2 MB Flash and 1 MB SRAM on the STM32H747 (U1) with 16 MB of NOR Flash
with the AT25SF128A-MHB-T (U8) as well as 8 MB of SDRAM with the AS4C4M16SA (U3). U8 connects over a QuadSPI interface to the main processor (U1). U3 operates at a frequency of 166 MHz.

The STM32 is probably running some form of RTOS and exposing some of it to the Arduino library.
