Hi all,
I'm going to start my first Geode-based project. I was googling around to understand which debugging techniques are available for this processor. So far I found: * (old fashioned) burn boot flash and see what happens (flash programming can be performed with external programmer or via JTAG) * ROM emulator (see for example http://wiki.laptop.org/go/ROM_Emulators_for_OLPC or http://www.tech-tools.com/er3.htm)
I'm wondering if it is possible to avoid the long burn-debug-recode cycle. For example, in case JTAG debugger is available, I should be possible to download the boot code in RAM (on-chip or external) and execute it under debugger control (I often used this technique in ARM/PowerPC-based embedded systems). I was having a look at Geode LX databook and I found that the GeodeLink Control Processor provides 1KB SRAM that could be suitable for this purpose. Anybody implemented such solution? Any comment or advice will be appreciated.
TIA, llandre
