Ecc error injection on Iram1 of Cortex-R5f

Hello all :

 Bacground:

 I am working on arm cortex-r5f ,  i want to inject 1/2bits ecc error  in Iram1  .

Specific:

 My most of the code is located in IRAM1, but my injection error function code is located in TCM to avoid  disturbing.

Issue:

When i am injecting 1/2bits error whitout  taking the initiative to visit Iram1,when stepping the below figure highlight "bx r14" , i find that  the error status has been set 1 ,please see the second figure2.

My problem:

can "bx r14" visit Iram1,but this command is loacated in TCM?
