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.
After launching the build_all.sh command the following folder will be created in the armgcc folder
- ddr_debug: containing DDR binaries compiled in debug mode (stripped: no symbols available)
- ddr_release: containing DDR binaries compiled in release mode (not stripped: symbols available)
- debug: containing TCM binaries compiled in debug mode (stripped: no symbols available)
- release: containing TCM binaries compiled in release mode (not stripped: symbols available)
Further details about memory mapping are available in i.MX 8M Applications Processors Reference Manual paragraphs:
- 2.1.2 Cortex-A53 Memory Map (pag 496)
- 2.1.3 Cortex-M4 Memory Map (pag 498)
JTAG
The VAR-DT8MCustomBoard exports the DART-MX8M JTAG signals through J29, a standard 1.27" 10 pin header.
Here the pinout
| pin | signal | description | pin | signal | description |
|---|---|---|---|---|---|
| 1 | JTAG_VREF | JTAG IO reference voltage, connects to SOM_NVCC_3V3. |
2 | JTAG_TMS | JTAG Mode Select signal |
| 3 | GND | Digital Ground | 4 | JTAG_TCK | JTAG Clock signal, requires 10K pull down. |
| 5 | GND | Digital Ground | 6 | JTAG_TDO | JTAG Data Out signal |
| 7 | GND | Digital Ground | 8 | JTAG_TDI | JTAG Data In signal |
| 9 | JTAG_NTRST_C | JTAG Reset signal | 10 | NRST_CON | Programmer Reset, used to put the SOC in reset state. |
Please refer to board schematics for further details.
