We are designing an audio system (firmware and board) that use ADSP-21569.
The firmware is based on SigmaStudioForSHARC-SH-Rel4.5.0 Target demo for 21569.
For hardware design I used ADZS-21569-EZ-KIT as a reference.This eval board use an 8Gb DDR3 (part number IS43TR16512BL-125KBL.)
Since we don't need such a huge ram, we would like to replace it with a smaller memory like the one that Analog use in the ADZS-SC589-MINI.The part number is: MT41K128M16JT-125 and seems to be pin-to-pin compatible.
My question is:- is this RAM p/n usable with ADSP-21569?- what modifications are needed in firmware for correctly initialize the DSP and the system with this ram (Reference firmware is in "SigmaStudioForSHARC-SH-Rel4.5.0\Target\Examples\Demo\ADSP-2156x\ADSP-21569" )
I hope that there is a way to configure this RAM because in a few days we will receive first board samples and 2 of 8 boards are assembled with this part number.
Thanks in advance for the support
Can anybody help me?
