Hello Mr kerry zhou, Yes, you can perform boundary scan tests using the LA-3050, in particular for NXP's RT1050. For more information about Boundary Scan, you can check our User Guide (https://www.lauterbach.com/pdf/boundary_scan.pdf) and NXP's Introduction to Boundary Scan of i.MX RT Series (https://www.nxp.com/docs/en/application-note/AN12919.pdf and https://www.nxp.jp/docs/en/application-note/AN13507.pdf). I am assuming that you are interested in Automated Board Test (page 33 in the mentioned User Guide), please try to use the WAIT command (https://www.lauterbach.com/pdf/practice_ref.pdf#page=95) after performing boundary scan (BSDL.RUN) and let me know if this meets your requirements. Please don't hesitate to reach out if you require any additional assistance.
