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
