开发板是 Sipeed Lichee RV,系统镜像是 LicheeRV_Tina_dock_hdmi_8723ds.img ,利用了 Tina Linux 中魔改的 uboot,其中包括了 bootr 命令来给 DSP 加载 firmware。
LicheeRV_Tina_dock_hdmi_8723ds.img
=> echo $(boot_dsp0) sunxi_flash read 45000000 ${dsp0_partition};bootr 45000000 0 0 => sunxi_flash read 45000000 ${dsp0_partition};bootr 45000000 0 0 dsp0:uart config fail dsp0:gpio init config fail dsp0:find section err
在 /etc/fw_env.config 中添加 /dev/by-name/env /dev/by-name/env-redund 之后通过 fw_setenv 编辑 bootdelay
/dev/by-name/env
/dev/by-name/env-redund
fw_setenv
dd if=dsp.elf of=/dev/mmcblk0p5

设备树内没配置dsp相关参数,启核失败
Sorry, something went wrong.
是 FreeRTOS 的设备树吗? 我看了 https://github.com/100askTeam/NezaD1_u-boot-2018/blob/master/drivers/dsp/sun20iw1/dsp.c#L129 uart config fail gpio init config fail find section err 都在 sunxi_dsp_init 函数里
uart config fail
gpio init config fail
find section err
sunxi_dsp_init
是uboot的设备树,描述了dsp核心分配的uart,io,还有efl解析地址,入口地址等
另外在适配linux下的remoteproc驱动之后可以使用linux的rproc框架启动dsp

,利用了 Tina Linux 中魔改的 uboot,其中包括了 bootr 命令来给 DSP 加载 firmware。uboot 命令行下加载 firmware 报错
修改 bootdelay
在 /etc/fw_env.config 中添加
/dev/by-name/env
/dev/by-name/env-redund
之后通过
fw_setenv
编辑 bootdelay制作 dsp 分区
dd if=dsp.elf of=/dev/mmcblk0p5
