读取文件会覆盖保留的内存。无法加载'hello_world.bin
Reading file would overwrite reserved memory. Failed to load 'hello_world.bin
我有带载板的 imx7d-pico。这台微型电脑
经常用于 Android 事物。 PDF（数据表）轻松
找到了。
我（在过去两周）一直在尝试本教程：
https://github.com/TechNexion/freertos-tn/tree/freertos_1.0.1_imx7d
export ARMGCC_DIR=${HOME}/gcc-arm-none-eabi-4_9-2015q3/
after ./build_release.sh I do
sudo cp ${HOME}/freertos-tn/examples/imx7d_pico_m4/demo_apps/hello_world/armgcc/release/hello_world.bin
/media/neuberfran/boot
ls mmc 0:1 (result command in U-boot)
10572 hello_world.bin
then:
=> fatload mmc 0:1 0x7F8000 hello_world.bin (with issue)
** Reading file would overwrite reserved memory **
Failed to load 'hello_world.bin
=> dcache flush (I can't)
=> bootaux 0x7F8000 (I can't)
