Part Number: TMS320F280049 Tool/software: Code Composer Studio Hi, We have been using the TMS320F280049M control card with the control card Docking Station (R4.1) without issues, but yesterday, in a usual code change + code flashing into the board work, the Microcontroller doesn't allow being programmed anymore. We're getting the following problem: C28xx_CPU1: Warning: Failed unlocking device (zone 1) after reset. C28xx_CPU1: Warning: Failed unlocking device (zone 2) after reset. C28xx_CPU1: Trouble Setting Breakpoint with the Action "Remain Halted" at 0xc0be: (Error -1066 @ 0xC0BE) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 7.0.48.0) C28xx_CPU1: Breakpoint Manager: Retrying with a AET breakpoint C28xx_CPU1: Error writing the PLL values. (Flash algorithm returned error code). Operation cancelled. C28xx_CPU1: File Loader: Memory write failed: Unknown error We tried with a Hello World Demo proyect from CCS, just to be sure that the problem is not in our code. If we use the Flash linker command file we get the above message again, if we use the RAM linker command file we get the following one: C28xx_CPU1: File Loader: Verification failed: Values at address 0x000F5@Program do not match Please verify target memory and memory map. Any help would be aprecciated, as it looks to us as if this chip is broken, locked or something like that... Best regards, Oier
