So totally 0x8afe8 = 555K bytes memory in XIP is used.
1.5.2.4
Available Heap Size
When calculating total used memory size, available heap size after WLAN association and BT connection needs to be considered. In the above
case, it is 56096 bytes.
Finally, you can use total SRAM 476K bytes to subtract these sections of memory to obtain totally free global memory and free heap in SRAM.
Formula is as below:
SRAM free global memory: 476K ─ “A4” ─ “P1” = 476*1024 ─ 96983 ─ 384968= 5473 (bytes)
Available heap: 56096 bytes.
Totally free SRAM memory and heap: 5473 + 56096 = 61569 (bytes)
Totally free PSRAM memory: 4*1024*1024 – 338 * 1024 (A7) = 3848192 (bytes)
