Other Parts Discussed in Thread: CCSTUDIO
Hi all,
I am having issues with creating a JavaScript DSS script that writes data directly to the internal flash memory of a TMS320F280049C. I am trying to write a debug script that will allow one to debug an application that executes after a bootloader. I am using a modified version of the F280049C flash kernel that TI provides, which uses a 'key' at the beginning of the application section of flash to indicate whether there is a valid application. I need to write this key manually in the DSS script, as this will be erased when the program is loaded into flash in the debug session.
The DSS script is attached below. After resetting, erasing, and loading a program, I attempt to write the key value manually to flash in lines 213 to 227. The default F280049C GEL script specifies the destination address as read-only, so the memory.map.add API call is used to indicate that we should have R/W permissions in the 0th internal flash bank (0x80000-0x8FFFF). We can successfully read the address 0x82004 as being empty (0xFFFF). However when trying to load data in from a binary file containing the hex value 0x5B5B using the memory.loadRaw call, I get the following error in the Rhino JS debugger:
loadRaw: ENTRY nPage: 1 nAddress: 0x82004 sFilename: data.txt nTypeSize: 16 bByteSwap: false
waitUntil: ENTRY timeout: infinite
SEVERE: C28xx_CPU1: Data verification failed at address 0x82004
I have not been able to figure out what the issue is. Clearly we are able to write data to flash in the memory.loadProgram call, but not using memory.loadRaw. I have been through the Data Verification Errors page, but this has not presented any solutions. I should note that the code security module has not been activated on the device, so we do not need a password to access the flash.
Performing the equivalent actions in CCS also does not work; modifying the GEL file to give the 0th flash bank write permissions and then using the memory browser to fill the address; this also produces a Data Verification failure.
The device under debug is a TMS320F280049C on a TI F280049C LaunchPad development kit. I am using CCS v10.3.0 on Windows 10 Pro, v10.0.19042.
