I am using a lauterbach JTAG model LA-3500 DEBUG-USB3 for ARM9 with Denebola board based on CX3.
When I flash my own bootloader in SPI, It is not possible to debug with JTAG using the following command:
D.LOAD D:\Dev\SmileFW\Bootloader_v2\CX3\Bootloader_v2\Release\Bootloader_v2.elf /NOCODE
On the other hand if the spi is empty (full of 0xff) It is possible to step , put break point .
I don't figure out why it is not possible to debug with SPI flash loaded ?
Solved! Go to Solution.

Hi,
>> My question is how to debug a bootloader loaded in Flash and above all is it possible?
Not possible, JTAG cannot debug if the bootloader/application firmware is loaded into Flash.
You can debug the same bootloader (which is loaded into Flash) by loading into RAM through JTAG.
