Hi, I am a new user for dsk5402. Now, I try to boot dsk5402 from flash. I follow the document and use flash utility. Below is the comment of flash.txt " ? Flashu.exe - flash utility. ? 5402hex - Contains sample HEX file to program DSK flash. Instructions To test the flash utility, make sure the jumper setting is set for HPI boot and type the following: flashu 2 -l blink02.hex NOTE: Flash programming takes at least 25 seconds since the entire flash is erased before being programmed. A 20-second delay is inserted to give the device enough time to completely the erase operation, resulting in the delay. Remove the HPI BOOT jumper setting to enable flash boot, power-down the board, and then power it back up. The blink program should boot from flash, blinking all three LEDs in sequence. Boot Jumper Settings HPI boot: JP2 pin 1&2 connected Flash boot: remove jumper " I follow all steps. I can see the message of flash erase ok and program success, But I can not see the LED blink after repower and remove jumper on JP2. I want to know if I lose any setting or do anything wrong. Thanks!!!!!!!
