Since current kernel do not have devicetrees for board which I used for testing, this RFC patchset includes this too. For testing I used this simple counter written in ASM: ====================================== .syntax unified .text .thumb .int 0x10020000 @ Initial SP value .int reset + 1 reset: mov r0, #0x55 ldr r1, =(0x40) 1: str r0, [r1] add r0, 1 b 1b /* Dummy data, required by remoteproc loader */ /* Please FIXME, this part seem to be incorrect */ .data .section .resource_table, "aw" .word 1, 0, 0, 0 /* struct resource_table base */ .word 0 /* uint32_t offset[1] */ ============================================================ compiled with: ${CROSS}as -o imx7m4.o imx7m4.S ${CROSS}ld -Ttext=0x0 -o imx7m4.elf imx7m4.o cp imx7m4.elf /srv/nfs/sid-armhf/lib/firmware/rproc-imx_rproc-fw Functionality was confirmed with current OpenOCD master. OpenOCD cfg file can be found here: https://github.com/olerem/openocd/blob/imx7-2017.06.14/tcl/target/imx7.cfg Comment and suggestions are welcome.
