Can 1243 cascade radar switch linux and rtos systems through serial commands?
I want to switch between linux system and rtos system through software instead of replacing files in SD card

Hi,

I don't think that is possible to switch the OS (dual boot) with the given system.

Regards,

Jitendra

Thank you for your reply, because I need to implement this function now, so is it possible to choose to jump to the kernel or rtos in uboot

Today I thought of an idea. The hardware has SD card boot and USB boot, so is it possible that I put the linux system in the SD card, and then put the rtos system in the U disk, when the power is on normally, enter uboot, if I need to enter linux and enter "boot", if I need to enter rtos, enter "usbboot". If I need to implement rtos online upgrade later, can I import the rtos firmware into a U disk under linux and replace it?

You could use the network file system as well where you save the binaries for the IPU and other cores in the firmware folder. However note the A15 continues to run Linux when you boot the Linux SD card, so you need to build a Linux+Vision SDK build for IPU codes running RTOS in conjunction with A15 running Linux. So in effect, if you would like to run the complete RTOS use case (no Linux at all) and Linux use case, you would need 2 SD cards.

Thanks and Regards

If you also agree that I can use an SD card and a USB boot at the same time, is there any relevant document that can tell me how to make a USB boot, I tried to make a USB using the SD card today, but it failed. The way of network file system can be done as the second solution, thank you

Kindly note we have not validated USB boot on the Cascade Radar EVM.

There is some information regarding USB boot in the below link, but since we have not validated this on the Cascade Radar EVM.
