linux+freertos demo, how to know Linux run rightly?
I use TX2 board. I use TFTP in uboot to download bao.bin. The uboot IP is set as below: setenv serverip 192.168.42.16 setenv ipaddr 192.168.42.15
The UART log is： tftp 0xa0000000 bao.bin;go 0xa0000000
Starting application at 0xA0000000 ...
Bao Hypervisor BAO WARNING: smmuv2 does not support coherent page table walks Bao FreeRTOS guest Task1: 0 Task2: 0 Task1: 1 Task2: 1 Task1: 2 Task2: 2 Task1: 3
So，it looks like that the FreeRTOS run OK. But I dont know if the Linux run OK too. In README.md, it said that Linux has the static IP(192.168.42.15), but I cant ping it sucessfully and cant ssh it too. So ,what's wrong with Linux? How to debug?
I believe it would be hard to debug on TX2 without any kind of external debugger. This was exactly my experience. I'd suggest changing the configuration to remove the freertos guest, while assigning the available uart to the Linux guest (also change the Linux guest device-tree to add the uart). Then with access to Linux through the serial console, try to investigate further why the ssh connection is not established.
Also, are you using our branch of TF-A? This is needed to setup the correct stream ids so the the SMMU correctly translates DMA requests from the ethernet controller.

I check that the TX2 has two UART, right? So, do you know how to config anohter UART to Linux？
When I was working with the TX2 I was not aware of a second UART available in the pin header. But if its there, after figuring out its MMIO region and associated interrupt there are two steps:
- Adding the UART to Bao's Linux guest VM configuration in the device list.
- Adding the corresponding UART node to the Linux device tree.
Also you probably need to add the Linux command line parameter console in the chosen's node bootargs property.
Hi, josecm. I have added the TX2 UART1 to Linux, it works now. But, the network still not work. I use ifconfig find there is no network device except lo. I checked the boot log, not find any error

So， what's the prolem, can you give some ideas?
It seems there is some issue with the tx2 bpmp driver. Are you using the same linux guest configuration as provided in the demos?

Yes, I use the configuration in the demos except add the UART1 config. Below is the configuration: /dts-v1/;

Any developments on this? If not, I will try to find some time to reproduce your issue.

Not yet.
Were you able to solve this? If so, what was wrong and how? If not, are you still trying to solve this? In this case I'll try to reproduce in the next couple of weeks, otherwise I'll close the issue.
Sorry，these days I have some other work to do, no time to debug this problem any more. If you can have a look at it, appreciate it.
