Hi all,
I am hoping someone can help with a CW TAP issue I have encountered.
We have 2 CodeWarrior Ethernet TAPs. One works fine with no issues. The other did work fine but has recently stopped working.
The problematic TAP seems OK in terms of network connection and USB connection. However, if I try to erase or program it will do the following:
- Connect via network OK (IP address printed)
- Status: target initialization…
- At this point it will either hang on initializing and just get sit there indefinitely (Status will report: Initializing……………………………………………………..)
- Or it will complete this step quickly and hang on erasing (Status will report: erasing……………………………………………………..)
- Sometimes it will pass and report “Erase command succeeded” but if I run a Blank Check it will instantly return an error “Blank Check failed”
Here is a copy from the logs after I tried programming…
======================================================================
=== Execute: Blank Check
=== Timestamp: Wed Nov 8 14:59:27 2023
=== Flash Device: LH28F016SC
=== Flash Organization: 2048Kx8x4
=== Flash Mem Start Addr: 0xFF800000
=== Flash Mem End Addr: 0xFFFFFFFF
======================================================================
Informing other connection clients that the target is being 'clobbered'.
Loading Flash Utility Driver at: 0x00000000
Performing Blank Check from 0xFFA80000 to 0xFFABFFFF ... Failed
The Blank Check algorithm was interrupted during execution.
Please check if the flash base address is correct or if there are any flash devices mapped inside the selected memory space.
If a custom target initialization file was used then check the following parameters: flash base address, flash bank size and flash bank port size.
Other information about the TAP configuration (note these settings work perfectly on the other TAP)
Interface Clock Frequency 16 MHz
Mem Read and Write Delay 0
I have tried different computers and different target devices with the same outcome. The issue follows the TAP. When I watch the TAP's LED's I note that the TX/RX LED will flash green followed by an orange flash. This happens when the software just sits there reporting "initializing".
Any help on this issue will be most appreciated.
Cheers,
Steve
