Original question:
AM2634: How to build data (.c and .h) without main function?
Hello,
I want to write a pattern in my application and read it from SBL after executing a reset.
What type of reset I should execute?
What are the types of resetting the target support?
Yours,
We don't explicitly state/guarantee the content of the RAM can be preserved after a reset cycle. You should treat the RAM content as suspect for corruption after a reset cycle and take steps to validate the contents. You can not assume the device will ensure the contents are preserved even if it seems to act like it on the bench.
When a reset happens in the middle of a write operation to the RAM, it can result in corruption of the RAM contents as the timing protocol to the RAM may not be met.
AM263x device supports PORz HW cold reset, HW Warm reset, SW warm reset, WDG reset , and debugger reset:
The SW reset, CPU reset doesn't clean the content of the RAM.
