Thanks for confirmation. So the real problem is eLBC ? What happens if I access other devices on eLBC (e.g. FPGA) simultaneously with NAND or NOR ?AFAICT, the problem is NAND being accessed simultaneously with anything else on the eLBC (at least GPCM -- not sure about UPM). Instead of delaying the memory-like transaction until the NAND special operation has completed, it seems to just abort the NAND operation. eLBC can't really tell the difference whether you've got NOR or FPGA hooked up to a GPCM chip select, so the problem should still apply.
Are you aware of Freescale plans to fix the problem in new silicon revisions ? Also, can you please tell what CPUs are affected by this, except 8536 and 8572. Thanks a lot. Felix.
