How to simulate the bootloader with flash S25fs256s verilog model for pulpino? - zhouqiang - 05-25-2019
Hi,
I want to try to simluate the bootloader with flash S25fs256s, so that I can simluate with the flash. I have found the verilog model of S25fs256s according to https://github.com/pulp-platform/pulpissimo/tree/master/rtl/vip/spi_flash, and I have instantiated the generic pad for each signal coming from my SPI model according to https://github.com/pulp-platform/pulpino/issues/16, and in order to test boot_code, I changed MEMLOAD on https://github.com/pulp-platform/pulpino/blob/master/vsim/tcl_files/run.tcl, from PRELOAD to STANDALONE. I instantiated the flash module in the pulpion_top file, but when I run "make testSPIMASTER.vsim" or "make helloworld.vsim" , but still encounter the error "RX string: ERROR: Spansion SPI flash not found” ，can someone tell me how to deal with the error? How can make it to find the Spanison SPI flash ?
