Hello Oleksij, On 17-06-14 22:48:52, Oleksij Rempel wrote:Hallo all, this is RFC patchset to provide remoteproc functionality on imx7d SoC. 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.Have you by chance also tried testing this with FreeRTOS code running on the M4 side?
no, currently my priority is to provide basic functionality with easy understandable target code and dependencies.
