Other Parts Discussed in Thread: HALCOGEN, RM57L843
Hello there,
The appearance is weird. I use XDS110 USB dongle to download/debug a custom made TMS570LC4357 board, and its possible that board may not able to power up after first reset. The steps to re-create issue is:
1. Connect target board
2. Erase and download program
3. After finish, power off entire board, and re-power board. By now everything runs smoothly.
4. Power off the board again, and then power up. Now it goes into asynchronous data abort. No any extra information to locate error at all! Note that from now, reset is not an option to bring the board back to normal. Only re-download programme can make it run one more time.
I found that this issue may relates to how data are stored in flash/memory. If the problem occur, rebuild the project can not fix the issue. However, modify the scatter/link file to randomly re-locate codes/variables bring chances to remove the bug. In an other words, if the project is working good, adding new codes/variable may introduce this issue.
Project has been stuck by this for more than a month. Please kindly help. What could possible wrong....? Thx!
