TMDX570LC43HDK: the RED error indicator is always on

NA GAO

Part Number: TMDX570LC43HDK

After the new project is built, the RED error indicator is always on.I checked the connection below：but the supplied CMD file cannot be opened.The program cannot run after modifying flash settings.

Console always shows:CortexR5: GEL Output: Memory Map Setup for Flash @ Address 0x0CortexR5: GEL Output: Memory Map Setup for Flash @ Address 0x0 due to System Reset
CortexR5: GEL Output: Memory Map Setup for Flash @ Address 0x0 due to System Reset

The routine on the official website can't run either.

Hi Na Gao,

Are you able to connect your JTAG emulator to the device? The HDK has built-in xds100v2 emulator, and it also supports external emulator using 20-pin ARM JTAG header.

If the JTAG connection is lost after the program is loaded to flash, the problem might be caused by the code you have programmed. The code in the flash makes the CPU enter an exception state repeatedly, and the CPU is not able to enter a debug state.

Please try this procedure to let CPU enter a debug state:

Open the target configuration window, and launch the selected the configuration
Switch to debug window.
Press the reset (nRST) button and hold it.
Click “Connect Target” immediately after you release the nRST button.
The board should be connected after couple tries.

Hi Na,

Under certain circumstances Cortex-R4/R5 can perform SPECULATIVE Instruction prefetch and SPECULATIVE data prefetch beyond the address ranges defined by the application image.

So the ECC values for all of the Flash memory space (Flash banks 0 through 6) must be programmed into the Flash before the program/data can be read. This can be done by generating the correct values of the ECC for the whole flash using linker cmd script.

Please see my example of ECC generation using linker cmd script:
