Reading the reference manual of STM32F4xx (RM0090), I need some explanation about the physical remap in FMC.
Page 71-72, §2.4, the interpretation of table 4 is not clear. Should I understand that when in mode Remap in FMC:
if MEM_MODE=010b (SYSCFG §9.3.1 page 298) :
NOR/PSRAM bank1 (64MB) goes from 0x0000 0000 to 0x03FF FFFF
NOR/PSRAM bank2 (64MB) goes from 0x0400 0000 to 0x07FF FFFF
and if MEM_MODE=100b (SYSCFG §9.3.1 page 298) :
the lower 128MB (out of 256MB) of SDRAM 1 are mapped from 0x0000 0000 to 0x07FF FFFF
(and the upper 128MB of SDRAM 1 are not accessible)
Because what I read in Table 4 doesn't look logical / correct. How does it exactly work ?
Thank you !
