TMS320F280x SDFlash Programming Utilities
F280x SDFlash Algo V1.1
Texas Instruments Inc. 19
CAUTION
The One Time Programmable Block (OTP) can only be programmed once.
The OTP block cannot be erased.
CAUTION
Do not press the SDFlash STOP button during the erase operation.
Pressing STOP will halt the CPU before the Erase algorithm completes. This can leave the Flash in a
depleted state or result in unknown Code Security Module passwords and lock the device
permanently. If you feel your device is in a depleted state (cannot be erased) then try the depletion
recovery algo.
Other conditions that can cause the CPU to halt prior to the completion of the Erase algorithm (e.g.,
power loss, device reset, PC crash, etc.) can result to the same problem described above.
Pressing STOP when executing the frequency toggle test described in section 9.3 is ok.
9.1.4. Select OK and save the project: File->Save Project
