Hi igorpadykov

I'm my custom board I don't have SD card but I am booting from ds5(loading in DDR and running from it) prompt is coming in hyper terminal

Ai board supports nor flash I have seen it but can I do this like flash related #defines I will copy from mx6dlsabreai.h file and put into mx6dlsabresd.h and than run now will it work for flashing u-boot one more thing I want to mention that sabre ai board have atmel flash I think but mine is spansion

I am facing problems with eim bus

Like address 0 to 14 is coming when CS comes,address 15 is always high but when CS comes it becomes low and address 16 to25 are fixed according to my address there are not changing with cs, I am veryfieng in scope with arm ds5 ice. I am doing all pads configuration also.

I am little bit confusing with eim address bus in shifting and non shifting mode (AUS bit) can you explain if I set unshift mode and DSZ is 1,2,3 than how address appears on bus for each setting

In this regard your support is very helpful to me

Hi saida

one can test eim with nor using SDK eim_test.c

"MX6_PLATFORM_SDK "

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6Q&nodeId=018rH3ZrDRB24A&fpsp=1&tab=Design_Tools_Tab

for spansion flash one will have to modify sources and add its ID check.

Reagrding AUS bit, it may be recommended to use default (shift) mode, use

connections given on Sabre AI schematic

"I.MX6_SABRE_AI_DESIGNFILES"
