Memory types
The SDK allow linking using 2 different memory types: DDR, TCM.
Here is available a short summary of memory areas used by Cortex-M4 as described in related linker file.
| memory type | M4 memory area | A53 memory area | memory lentgh | linker file |
|---|---|---|---|---|
| DDR | 0x80000000-0x801FFFFF (code) 0x80200000-0x803FFFFF (data) 0x80400000-0x80FFFFFF (data2) |
0x80000000-0x801FFFFF (code) 0x80200000-0x803FFFFF (data) 0x80400000-0x80FFFFFF (data2) |
16MB (DDR) | MIMX8MQ6xxxJZ_cm4_ddr_ram.ld |
| TCM | 0x1FFE0000-0x1FFFFFFF (code) 0x20000000-0x2001FFFF (data) 0x80000000-0x80FFFFFF (data2) |
0x007E0000-0x007FFFFF (code) 0x00800000-0x0081FFFF (data) 0x80000000-0x80FFFFFF (data2) |
256kB (TCM) + 16MB (DDR) | MIMX8MQ6xxxJZ_cm4_ram.ld |
All linker files are locate in the armgcc folder of each demo
