DEBUG SPL with AM3352, Eclipse Juno, JLink Pro, Linaro 4.9.2 toolchain.

Hello,

I have a custom board DDR3, TPS6917 PMIC, SPI boot with NAND flash.

I am trying to debug the SPL by loadinbg the SPL binary, and then loading symbols from the ELF file. All is good, I can start the debugger and I get this window set....

As you can see the SP is pointing at the start vector, and the CPSR has been preloaded to a value with ARM instructions set.

This all looks good but on the first step I get an undefined instruction trap.

I'm confused? This is the exact code that is present in init.S, so its valid startup code.

I can compile the bootloader example with a bare-metal toolchain and run that up. But This little glitch has dumbfounded me.

All i can think is that my register setup is not correct. The CCS instruction for debugging SPL say just clear the T-bit in CPSR and you should be good to go.

Thanks for any info,

Eldon.
