Trouble with redboot on SPANSION S29GL512N

[Maxin B John]

Dear all, I have compiled ECOS to support AMD/SPANSION S29GL512N flash for EP9301 . I have compiled the the redboot.bin but on booting , the system hangs. The flash_am29xxxxx_parts.inl is modified like this #ifdef CYGHWR_DEVS_FLASH_AMD_S29GL512N { //AMD/SPANSION S29GL512N long_device_id:true, device_id: FLASHWORD(0x227e), device_id2: FLASHWORD(0x2223), device_id3: FLASHWORD(0x2221), block_size:0x20000 * CYGNUM_FLASH_INTERLEAVE, block_count:512, device_size:0x4000000 * CYGNUM_FLASH_INTERLEAVE, base_mask:~(0x4000000 * CYGNUM_FLASH_INTERLEAVE-1), bootblock : false, banked :false, }, #endif Please let me know if anyone had successfully compiled the redboot with SPANSION S29GL512N with EP9301. Thanks & Regards, Maxin B. John

Make sure your memory map (which on ARM includes some
assembly tables) have been adjusted to handle the FLASH.
If they are not able to handle the entire size (64MB in
this case), then RedBoot will hang/die.

Dear Gary Thomas,

 Thank you very much. But I am a bit consfused. I would like to know
where I need to modify that. So how user can change the memory layout
if he wants to change ?
   I not sure  that I am suppossed to change the *.ldi  files. So am I
suppossed to change the  size in  *.h or *.mlt file and recompile
again ?

Thanks & regards,

The current files (as provided by Cirrus) only map 16MB for FLASH.
You'll need to make adjustments in 3 places to handle your 64MB device.

Dear Gary Thomas,

 I have modified the files as given below..

 But still the redboot is not booting.
Please help.
