According to the EE-345 note, I use SPI flash boot mode and run the second stage loader on sharc 21479. After I write the .ldr file to the flash, I am running software reset, I want the DSP run the new program and I failed. But if I only power down and power up the DSP, the new program work. I want to known how I can reset the DSP after I write the ldr file to flash and the new program will work?
Hi,1) Is it possible to probe and share the SPI signals (clock, MISO) are toggling as expected after reset and look similar to when you do a power on reset.2) In order to debug why the application is not booting from the flash after reset, we would suggest you to kindly refer to the below FAQ from below link:ez.analog.com/.../faq-how-to-debug-a-target-board-which-boots-from-flash3) Please refer this below ezone thread's.ez.analog.com/.../adsp-21489-spi-bootez.analog.com/.../sharc-21477-software-reset4) Can you first try with simple LED application?Regards,Anand Selvaraj.
