The s/w that came with the board appears to have the redboot source but I think it is a eCos 2.x version. Is there an existing package for this board or is there a way to 'import' it from the 2.x source? Thanks for any pointers in getting going in the right direction!This board is not part of the public tree. You should be able to get the original sources from Technologic SystemsI believe the source for the redboot is on the CD supplied from Technologic Systems, but I believe that it is for eCos 2.x tree. Can I just copy that over to the eCos 3.0 tree that I've installed or does it need to be 'Imported' via the config tool?As a starting point, you should be able to copy the directories containing the additional eCos HAL and driver packages from your TS7250 repository to an eCos 3.0 or eCos CVS repository and then copy the relevant "package" and "target" declarations from the ecos.db file in the root of your TS7250 repository to the eCos 3.0 or eCos CVS ecos.db file. Note that there is also a patch providing full eCos support (not just RedBoot) for a number of EP93xx parts: http://bugs.ecos.sourceware.org/show_bug.cgi?id=1000739 John Dallaway eCos maintainer http://www.dallaway.org.uk/john
Thanks for the suggestion!I think that I am making progress as at least I've been able to build the library and the tests.
Though I am not able to load the tests either via the 'Run Tests' or the Redboot 'load' command.
The 'load' command appears to indicate that the file is not linked correctly as I get the error message:
Abort! Attempt to load ELF data to address: 0x00008000 which is not in RAM.
I've tried configuring the Startup type: to RAM but I get a build error that the mlt_arm_arm9_ts7250_ram.ldi does not exist.
I am trying build and load via the Redboot monitor, is this the right method for building for that scenario?
Thanks again! I owe you more than just a couple of beers... --JJ-- -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
