MDM_IDL28 Getting Started

I purchased an MDM_IDL28.

I connected an ethernet cable and started the LMI Flash Programmer program. I selected the ethernet interface and put in the IP and Mac address.

It looked like the only way to see if I could talk to it was by hitting the program button, so I choose what looked like the safest thing: boot_eth.bin from
C:StellarisWareboardsrdk-idmboot_ethsourcerygxx

Well, it seemed to work since it reported that 3868 bytes had been programmed, but that's all she wrote. Now it appears dead. No blinking LED, nothing on the display, and it isn't getting an IP from my router. :(

So.. Do you sell the fine-pitch debug header adapter? I have a EKT-LM3S8962 dev kit also. Can this be used as a debugger to load something that runs?

Thanks very much for your time.

Re:MDM_IDL28 Getting Started

Unfortunately, you picked the single binary in the software package for the IDM that will cause this problem. The boot loader is a special case - it's the only binary that cannot be replaced by the boot loader that is flashed on the module. Your board now has 2 copies of the boot loader - the one that was there originally and a second one which is flashed at the wrong place (0x1000 rather than 0x0000 where it is intended to go) and which will likely be crashing your board when it is invoked.

To get round this, you will need to use your 8962 board as a JTAG/SWD adapter (as you suggested) and flash another application at address 0x1000 (any of the other binaries - hello.bin would be a good place to start). The fine-pitch debug header is supplied with the IDM RDK but not with the module and I don't know if it is available separately (I'll check). Instructions on using an EK board as a debug adapter can be found in the RDK-IDM User's Manual which you can download from [url=http://www.luminarymicro.com/products/rdk-idm.html]here[url].

Re:MDM_IDL28 Getting Started

Thanks very much for the reply. I constructed an adapter for the fine pitch debug header, and am using the 8962 board as a jtag debugger. It worked great with evaluation version of Codesourcery's IDE, and I already have my own simple app which is drawing on the LCD screen and using the buffered serial port support for I/O.

So far I'm very pleased with the product and especially the driver library and graphics library.

If Lwip and the Fatfs are as easy to get working as the uart and graphics, then I will be overjoyed.
