Code Conversion For GEL Files.

Gabriel Quintana said:

Is there a tool or something that can convert the GEL code into a C file used by this particular platform?

I do not know of such a conversion utility, however the GEL file is already very C like, and for the most part the configurations you want are just writes to registers so if you can convert a single write than you could do them all.

Or is there a C file around that does that initialization? Or is there any documentation that I can refer to in order to do the conversion by my self?

In general on a device like DM648 you would not necessarily write your own initialization code into the out file, at least not everything in the GEL file, as the DM648 supports an AIS based boot mode, meaning that the ROM boot loader will read an AIS script out of your flash to do what the GEL file does (primarily setting up the EMIF interface so you can write to external memory). This being said, instead of converting the GEL file settings to C code you would take the values it sets up and put them into the AIS image you write to flash, for details on the DM648 boot process and how to setup an AIS image please see http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=spraaj1c.

The link http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=spraaj1c is invalid now.

could you tell me what is the correct one now?

Thanks.

Certainly, it looks like they changed versions so it is now ending in d, in any case the link below should work.

What's the solution for the dm365 ?!

For DM365 you don't often use GEL files as you don't often develop for it with CCS as it is an ARM based product which typically runs a high level OS like Linux so there is not much collateral on using GEL files or CCS with the DM365. This being said, if you are booting a high level OS like Linux there are already advanced boot loaders available for the DM365 which cover the kind of initialization that would be done with the GEL file, primarily the UBL and U-Boot, which are included with the PSP of the DVSDK in source and binary.

Thank you for this information ,

I would use the sample of CCS with GEL file to test ,LED and GPIO , so i can't use it because i use now a linux OS ,  I tried to test GPIO Driver to set and read (GIO32)  for example in the board EVM DM365 , i can load the driver without problem and when i run the test driver no thing happen ??.

If you have a sample of the driver GPIO and test driver sample for the DM365 , thank you show me please.
