I have a custom board with DM8148. I'm using IPNC_RDK_InstallGuide's steps for write u-boot's first step . But when I load nand-flash-writer I get the follow problem:
CortexA8: Breakpoint Manager: Retrying with a AET breakpoint
CortexA8: Trouble Setting Breakpoint with the Action "Process CIO" at 0x8000a3ac: (Error -1066 @ 0x333C) Unable to set requested breakpoint in memory. Verify that the breakpoint address is in writable memory. (Emulation package 5.0.471.0)
I ensure that this address is in writable memory. Any suggestions?
