Help me! I am running sel4test on my TX1 according to the official tutorial, but I get a problem again and again. For the newly purchased TX1, I directly connected my Ubuntu host with UART serial port.
At the same time, I follow this instruction ( https://docs.sel4.systems/Hardware/jetsontx1.html ), pulled the latest sel4test project code, successfully ran ninja command and built images "sel4test-driver-image-arm-tx1". Everything seemed to be going very smoothly. I use the newly purchased SanDisk 64GB SD card to boot my image, which has been formatted in ext4 format.
Then I use command `sudo screen / dev / ttyusb0 115200` to open the UART serial port. After pressing and holding the power key for 1 second, and TX1 starts. Then I hit the Enter key to make TX1 cancel the auto boot default image and enter the u-boot interactive command line.
Then, according to the instruction, under uboot, I typed the following command to load the image and start from the address 0x82000000: ``` ext4load mmc 1 0x82000000 sel4test-driver-image-arm-tx1 go 0x82000000 ``` Finally, I failed to start sel4test as I wanted. After many repetitions, I got the same error. This is my output： ------------------------------------------------------------------------------------------------------------------------------------------ Tegra210 (P2371-2180) # ext4load mmc 1 0x82000000 sel4test-driver-image-arm-tx1 5247256 bytes read in 260 ms (19.2 MiB/s) Tegra210 (P2371-2180) # go 0x82000000 ## Starting application at 0x82000000 ...

I'm about to collapse. I really need your help. How can I solve this problem?
1. Why did I get this warning？ "Warning: gpt_cntfrq 19200000, expected 12000000" , It exists in this file "/sel4test/kernel/src/drivers/timer/generic_timer.c:21"
2. About reporting errors "failed assertion 'cap_get_capType(destSlot->cap) == cap_null_cap'". I found that the variable "(slot_ptr_t) (rootserver.tcb) ) -> cap.words[0] " is equals to 0xffffffffffffffff, so that the cap_get_capType(destSlot->cap) <=> (slot_ptr_t) (rootserver.tcb) ) -> cap.words[0] & 0x1full != 0 . I guess it caused the mistake, but i don't know why.
