I have designed bf533 dsp based custom card in which i have used AT49BV320 AS FLASH DEVICE. I have successfully loaded the *.ldr file Now driver is loaded and *.ldr file is successfully loaded in flash device.
Current problem is that when i boot the flash it is not giving correct
output . for this testing i monitored serial clock frequency in the two
1. programming through emulator and monitored the result, that gives the
corret transmit serial clock frequency.
2. Same program is loaded in flash and boot the flash the transmit clock
frequency not showing correct.
In my program i am taking continuous data to ppi port and send data
through sport1 to fpga.I have monitored Transmit serial clock .If i run
the program through emulator it shows correct serial clock(50 MHZ as per
defined transmit clock sport1_tclkdiv) .If the same program i have loaded
in flash and boot (boot the flash through AMS0 and boot mode 01)the flash
showing 20mhz .
And this value is consitent in many times power on -off the card.
Please suugest what would be the reason that in boot mode not giving
And how to read flash content in no boot mode.
Thanks and Regards,
