Issue with adding ssh key to review server

by sparlane＠gmail.com

Hi All, Sorry if this is the wrong list, I'm trying to submit a patch for tf-a and I'm currently unable to add an ssh key or generate an https password to use for authentication. Perhaps I am doing something wrong? I'm trying to use the settings here: https://review.trustedfirmware.org/settings/#HTTPCredentials to add an ssh key and I get the error message "Error 500 (Server Error): Internal server error Endpoint: /accounts/self/sshkeys" Any help is greatly appreciated. Thanks, Scott (sparlane)

How to trap aborts caused by TZASC?

by Chenxu Wang

Hi all, I want to test how to trap the aborts caused by TZASC. For example, when I use NS-EL1 (e.g., OS) to access a Secure region (configured in TZASC), it will generate an abort. But I am not sure how to trap it. I think it is an external abort, so I enable the SCR_EL3.EA=1 and write a handler. However I cannot trap it. Also, my other handlers in EL3 still do not report the abort. Thus, how can I trap a TZASC abort? If I want to route it into EL3 to handle, how can I do it? Sincerely, WANG Chenxu
