Other Parts Discussed in Thread: TMS320F2808, SYSBIOS, UNIFLASH
While programming the Board with target chip TMS320F2808, the error message is popping up for locked flash.
We explored for soultion and as found with the ti link :
http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/244748/858217.aspx
we followed the following steps for unlocking the target flash.the steps that we followed are as given below :
View > Target Configurations > Navigate to the configuration inside FlashingLeds-F28035 > Launch Selected Configuration (right click)
Run > Connect Target (C28xx) > Resume > Suspend
Tools > Memory Map > On-Chip Flash > Code Security Password > Unlock (button). Error because password is wrong.
Tools > Memory Map > On-Chip Flash > Code Security Password > Key 7 > Change from FFFF to FFFE
Unlock (button
Tools > Memory Map > On-Chip Flash > Erase Sector Selection > Sector A > Erase flash (button)
Terminate debug
Reset Experimenter’s kit
Debug example on hardware. Resume. Suspend. This works because the device is unlocked.
But we are still getting the error message :
C28xx: Flash Programmer: Device is locked or not connected. Operation cancelled.
C28xx: GEL: File: D:\Eaton\vineeta_code\LittleRedSBC_sysbios_29_11_13_DC4\Debug\LittleRedSBC_sysbios.out: Load failed.
We have configured the target clock for communication to board as 20 MHz in synch with the oscillator rating mounted on target hardaware.
We are not sure about the root cause for this issue mentioned above.
Please suggest the solution approaches?
