LAUNCHXL-RM42: Failed to load flash loader with IAR

The RM42 launchpad has a built-in xds100v2 emulator. Other RMx launchpads (RM46x, RM57x) use xds110 emulator. Is the emulator selected correctly? 

Hello QJ,

I've removed the JTAG resistors and I'm using the 14 pin header to debug the board. I have an external xds100V2 and i-jet. both of them acts the same.

I've investigated the problem with IAR support and they said I "locked myself out on the RAM" meaning the RAM is not accessible to load the flashing program.

This set up worked for me for almost  2 months, now, and the problem happens when I work on the startup code to implement CPU self tests (following the sample code in the SafeTI diagnostic library)

Hello QJ, 

This is the error I'm getting from Uniflash when trying to erase the entire chip:

[ERROR] CortexR4: Trouble Writing Memory Block at 0x8000300 on Page 0 of Length 0x20: (Error -1065 @ 0x0) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.4.0.00006)
