Hi,

i'm using STR711FR2.

When i'm trying to download F/W using Keil Ulink i get the message ''timeout error''.

The problem is that the WatchDog isn't shutting down when the download starts.

I tried to run an ini file before the download in order to disable the watchdog with no success.

I tried the following commands in the ini file:

1. _WDWORD(0xE000E000,0)

2. E INT 0xE000E000 = 0

3. MEMSET (0xE000E000, 2, 0)

questions:

1. What is the difference between these commands?

2. Any suggestions how to solve the problem?

Do not use ulink but the problem affects all debuggers.

I would say the watchdog is being activated before the ulink is able to stop the core. once enabled only a reset will stop the watchdog.

The only solution is to delay before setting the watchdog to give the ulink time to stop the core.
