i.MX7Dual HAB with M4

[urimashiach]

Hello

I'm using U-Boot based on v2018.11 + CONFIG_SECURE_BOOT.

The M4 hello world (FreeRTOS) example is not functioning when the U-Boot is compiled with CONFIG_SECURE_BOOT.

An attempt was made to load the example to the following sections:

• TCM (0x7F8000)
• OCRAM (0x910000)
• DDR (0x9FF00000)

Thanks,

Uri

Hello Yuri,

No messages are generated.

Is there a way to check the status the M4 core?

Thanks,

Hi Yuri,

It seems that the U-Boot is not affected:

U-Boot # tftp 7F8000 hello_world.bin
Using FEC0 device
TFTP from server 192.168.11.218; our IP address is 192.168.122.85
Filename 'hello_world.bin'.
Load address: 0x7f8000

U-Boot # dcache flush
U-Boot # bootaux 7F8000
U-Boot #

Thanks,

Uri
