The Asynchronous Read Memory Access Timing for the EIM in the Applications Processor Reference Manual refers to signal ADV, but I cannot find/map this external I/O. Does anyone know which output this is?

Please use EIM_LBA signal, according to Table 22-2 (EIM External Signals) of i.MX6 DQ Reference Manual :
"EIM_LBA Address Valid. This active-low output signal is asserted during

burst mode accesses to cause the external burst capable device to load

a new starting burst address. Assertion of LBA indicates that a

valid address is present on the address bus. Its behavior is affected

by the SWR, SRD, BCD, and BCS fields of the EIM_CSxGCR1

registers, the RADVA and RADVN fields of the EIM_CSxRCR1

registers, and the WADVA and WADVN fields of the

EIM_CSxWCR1 registers. In asynchronous mode, LBA length is

affected by the RADVA, WADVA, RADVN, and WADVN fields.

Minimum length of LBA signal in all modes is one EIM clock cycle".


Have a great day,
Yuri
