gicv3 interrupt init, interrupt trigger, interrupt handler at uboot command ( EL2 mode )

dongjoo99kim — Wed, 06 Dec 2023 09:24:14 GMT

Dear all.

I have developed imx8mq including cortex a53, gicv3 controller.

As i know, uboot can't support gicv3 interrupt init, interrupt trigger, interrupt handler by the uboot exception vector table.

But, I want to bring up gicv3 interrupt init, interrupt trigger, interrupt handler by the uboot exception vector table not routing to El1 or El3.

And, our uboot run at el2 mode.

My scenario is to bring up a gicv3 interrupt init, interrupt trigger at uboot command.

After trigger interrupt at uboot command, I want to get a interrupt handler by the uboot execption vector table not routing to EL1 or El3.

Is there any method to solve this problem?

Please, help me.

Thanks.

HI, How do you flash uboot binary into sd card. I am also flashed but it shows invalid partition 1. what are the things need to prepare sd card before flashing. can you share your thoughts?

BuildInfo:
- ATF 70fa7bc
- U-Boot 2019.04-04771-g4d377539a1

Run CMD11 1.8V switch
switch to partitions #0, OK
mmc1 is current device
flash target is MMC:1
Run CMD11 1.8V switch
Net:
Warning: ethernet@30be0000 using MAC address from ROM
eth0: ethernet@30be0000
Fastboot: Normal
Normal Boot
Hit any key to stop autoboot: 0
Run CMD11 1.8V switch
switch to partitions #0, OK
mmc1 is current device
Run CMD11 1.8V switch
** Invalid partition 1 **

Dear Hariharan1

I just copy the uboot image using usb sdcard reader from host PC.

Sorry. But, I can't answer the method to you what you request.

Could you share to me the method how to enable gicv3 interrupt init, interrupt trigger, interrupt handler at uboot cvommand ( EL2 mode) ?

Thanks.
