question: there is 3.3v DC votlage in capture function pin B12, P13.0 in TC387 with BGA292.  normally, it should be 0v.

what we did:

1. whatever we set this pin register  "no pull", "pull down", it doesn't work. 

2. we have tried to disconnect all component form this pin. we will still see this DC votalge in this pin.

do anyone have this issue before and provide solution or suggestion?

thank you!

hello infineon

    I meet a System Bus and Peripheral Errors DAE - Data Access Asynchronous Error (TIN 3)  trap on tc322 

DATR reg value is :0x00000008

DSTR reg value is :0x00000004

the DEADD register value is 0xAF000200   a DFLASH address

I have two question:

1. trap is a Store data type ,but why the DSTR  register load operation error is 1???

2.  This trap is Data Access Asynchronous error, how to understand the Asynchronous?   Is the PC address recorded in callstack when the trap raised is not the real  PC address that which caused the trap.

3.when trap raised ,  I read the callstack  found The instruction executed by pc is read a Dflash address but why this operation  raised a trap???

aurix development studio can't debug, the icon is gray.

how to solve this issue?

Hello,

Whether TSIM supports TC3xx series to debug application without hardware,  If yes then whether AURIX TC3xx - Free Entry Tool Chain is helpful to achieve mentioned purpose?

Thanks!
