writing to flash through generic tristate controller (Rc256mbp33 micron flash)
i opend generic tristate controller and selected intelp33256mb flash and applied with dame timing constraints. but when i am writing one 16 bit data and its reading fine . but when i took a data in array of 32 and in loop i am writing data and checking the ready bit .and then again writing untill the loop ends . now its reading uneven data from flash . am i doing some thing wrong . or i have to use buffer programming method for that one. can anyone help me with this856Views0likes2CommentsRe: cfi flash : code error 8 from nios2 flash programmer
hi, why cant i change the FPGA image and program locations after flashed, if i want to modify the program then there is no usb blaster after integration then i want to load the program through rs422 communication . how it is possible without modifying flash locations. even if we load through jtag memory location contents will be changed. please give me a solution for loading the program through uart-422 communication4.3KViews0likes0CommentsRe: cfi flash : code error 8 from nios2 flash programmer
in active parallel config we can access flash through tristate controller right. or we have to use only pfl . we can program through nios2flash programmer also .i had seen in document. only through pfl it is flashing when we initialize the memory content with hex file . otherwise it is not working through tristate controller and nios2flash programmer . can u tell me why i want it through tristate controller otherwise its not going to suit my aplication.will u please reply quickly.4.5KViews0likes0CommentsRe: Purchase of New Intel FPGA Development Board
hi james , can u help me with the flashing through genric tri state controller and nios 2 flash programmer because i got errors with that like error code 8 and i flashed with the quartus programmer that s working fine by memory initialization. i have active parallel config nor flash 256mb p3365nm technology2.8KViews0likes0CommentsRe: cfi flash : code error 8 from nios2 flash programmer
then what ip supports active parallel . can u show the process for active parallel booting in cyclone iii fpga . In cyclone iii fpga supports active parallel booting .i read it in the document . help me with booting process for cyclone iii active parallel flash .4.5KViews0likes0CommentsRe: cfi flash : code error 8 from nios2 flash programmer
ACtually ,i connected tristate controller in qsys, and assigned pins in pin planner and i programmed through quartus programmer but it is not booting ,i tried all the methods given in handbook setting the reset vector ans exception and also bsp settings nothing worked out. Without generic controller it is booting by initializing the onchip memory with the hex file . our flash is micron rc256p33tfe flash in genric tristate controller i applied intel pcp30256flash but it is not boooting . our booting method is active parallel. can i use tristate controller in active parallel . thank u4.6KViews0likes0CommentsRe: cfi flash : code error 8 from nios2 flash programmer
yeah that's working fine . but i dont want that ,i converted sof file to .flash file and write it in ox20000 onwards by receiving the data in .flash file through uart but it is not booting on power on . do we need to write other than converted sof file to boot up on power on . do i need to convert pof file to hex file and write that data from 0x20000 onwards but pof file is having other data than .sof file do we need convert pof file and write to flash i want to know that data . or any other suggestions . actually in all pdfs its mentioned we have to write from 0x20000 onwards reply fastly man, i had no time left.4.6KViews0likes1CommentRe: cfi flash in cyclone iii
