A 4GB fifo is valid? Add some constraints.
128 is valid, will update.
Nope, the width of this field is 8bits -> 256 bytes
correct me if I am wrong, the width of this field is 4bits -> 128 bytes
(based on QUAD mode) .
This has nothing to do with quad-mode. Its about how much SRAM amount of
SRAM is present to buffer INDAC mode data. For TI platforms this is 256
bytes.
See CQSPI_REG_SRAMPARTITION definition in your datasheet.
Agreed, Thanks!
Yes , I have gone through it , Intel and Altera SoC's SRAM(act as
FIFO)size is 128 bytes and TI has 256 .
BTW old legacy DT binding mentioned size is 128, as per your earlier
suggestion you have mention that
keep the contents from old dt bindings as it is, so shall I keep 128/256?
