7 core and Single Cortex M4 core.
8 Zephyr was ported to run on the M4 core. In a later release, it will also
14 - i.MX7 Single/Dual Cortex A7 (800MHz/1.0GHz) core and Single Cortex M4 (200MHz) core
19 - RAM -> M4: 3x32KB (TCML, TCMU, OCRAM_S), 1x128KB (OCRAM) and 1x256MB (DDR)
65 supports the following hardware features on the Cortex M4 Core:
117 The M4 Core is configured to run at a 200 MHz clock speed.
128 The Colibri iMX7D doesn't have QSPI flash for the M4 and it needs to be started by
129 the A7 core. The A7 core is responsible to load the M4 binary application into the
130 RAM, put the M4 in reset, set the M4 Program Counter and Stack Pointer, and get
131 the M4 out of reset.
135 The M4 can use up to 5 different RAMs. These are the memory mapping for A7 and M4:
138 | Region | Cortex-A7 | Cortex-M4 (System Bus) | Cortex-M4 (Code Bus) | Size …
140 … | 0x80000000-0xFFFFFFFF | 0x80000000-0xDFFFFFFF | 0x10000000-0x1FFEFFFF | 2048MB (less for M4) |
185 Below you will find the instructions to load and run Zephyr on M4 from A7 using u-boot.
216 M4<->Linux IPC using RPMSG
223 The boot process of the M4 core is handled solely by the Linux kernel using the RPROC
235 You need to modify your Linux device tree to add the M4 definitions:
238 - Reserve memory areas for the M4 so Linux won't touch them.
239 - Define the M4 remoteproc node for the drivers.
