Urgent ! BF706 Batch burning question.

Hi guys:

       Now,my customer was using BF706 to build a product.

       Now it has entered the stage of mass production. At present, the system is booted from flash. Now, multiple devices are required to burn code at the same time. Is there any relevant scheme? At present, it is a direct thimble burning flash mode.

       At present, the demand is urgent !

 

 

 

thanks!
