CC2642R-Q1: UniFlash CLI EraseSectors format

What is the command line format for erasing certain sectors of flash memory using UniFlash CLI?

This is not mentioned at https://software-dl.ti.com/ccs/esd/uniflash/docs/v8_0/uniflash_quick_start_guide.html#command-line-interface

However, EraseSectors is an available option:

$ uniflash -c ~/Documents/cc2642r.ccxml --list-ops
Executing the following command:
> /home/ksivasambu/ti/uniflash_7.0.0/deskdb/content/TICloudAgent/linux/ccs_base/DebugServer/bin/DSLite flash -c /home/ksivasambu/Documents/cc2642r.ccxml --list-ops

For more details and examples, please refer to the UniFlash Quick Start guide.

Cortex_M4_0: GEL Output: Memory Map Initialization Complete.

--- Available Flash Operations ---
Erase, EraseSectors, ReadPriBle, ReadSecBle, WriteSecBle, ReadPriIeee, ReadSecIeee, WriteSecIeee, BlankCheck

Hi Karthikeyan,

Use the -S/--list-settings option with a .* argument to show all available settings

--- Settings ---
- ResetOnRestart = false
- RestartOnSymbolLoad = false
- ClearBreakpointsOnLoad = true
- AddCEXITbreakpointAfterLoad = true
- AddCIOBreakpointAfterLoad = true
- AddSemiHostingBreakpointAfterLoad = true
- VerifyAfterProgramLoad = Fast verification
        Allowed Values:
        0. Full verification
        1. Fast verification
        2. No verification
- HaltOnConnect = true
- AutoResetOnConnect = false
- AutoConnectIfChildConnects = true
- DisableIntWhileAsmStepping = true
- DisableIntWhileSrcStepping = false
- DisableIntWhileRunning = false
- UseLegacyStopMode = false
- AllowInterruptsWhenHalted = false
- PoliteRealtimeMode = true
- AutoRunToLabelName = main
- AutoRunToLabelOnRestart = false
- AutoRunToLabelOnReset = false
- ConnectOnStartup = false
- EnableInstalledBreakpoint = false
- IgnoreSoftLaunchFailures = true
- PreventStepIntoAsm = true
- LowPowerRunMode = false
- KeepDebugPoweredAtDisconnect = true
- CIOTimestamp = false
- EnableSoftwareBreakpoints = true
- FileIODefaultDirectory =
- SyncBreakpointsAndSymbols = Synchronize breakpoints and symbols (with like cores), as well as execution
        Allowed Values:
        0. Synchronize execution only
        1. Synchronize breakpoints and symbols (with like cores), as well as execution
- ModuleDebuggingEnabled = Never
        Allowed Values:
        0. Never
        1. When modules are loaded and unloaded (intrusive on target execution, and requires a patched kernel)
        2. Whenever halted in the module load/unload routines (you must manually set breakpoints in the appropriate routines for this to work)
- ModuleNameList =
- ModuleSearchPath =
- FlashVerboseMode = false
- FlashEraseSetting = Necessary Sectors Only (Retain untouched content within sector)
        Allowed Values:
        0. All Unprotected Sectors
        1. Necessary Sectors Only
        2. Necessary Sectors Only (Retain untouched content within sector)
        3. Specific Sectors
        4. Do not erase sectors (program load only)
- ProgramLoadEraseSpecificInfo =
- ProgramLoadEraseSpecificText =
- CrcVerify = true
- FlashPageToggle = false
- FlashPageText =
- FlashPages = 0-5,8
- FlashPagesFilledWith = false
- FlashPagesFilledWithValue = 0x
- KeepCcfgSetting = false
- DisableBootloader = false
- DisableCpuDap = false
- WriteProtectionToggle = false
- WriteProtectionText =
- EraseActionChoice = Erase entire flash (You must reconnect to the target afterwards)
        Allowed Values:
        0. Erase entire flash (You must reconnect to the target afterwards)
        1. Erase specific flash sectors
- StandaloneEraseSpecificText = 0-5,8
- RetainBleSecondaryAddr = false
- OverrideBleSecondaryAddr = false
- DeviceBleSecondary = --
- RetainIeeeSecondaryAddr = false
- OverrideIeeeSecondaryAddr = false
- DeviceIeeeSecondary = --

Of these, EraseActionChoice and StandaloneEraseSpecificText should allow you to specify the flash pages you want to erase. You can then use the -b/--before option with the EraseSectors argument to carry out the instruction. Here is a relevant E2E thread: https://e2e.ti.com/f/1/t/752772
