Honored ContributorWe have a project of Nios I, my question is when we produce this board, we should program the flash using a normal programmer before it is put on PCB.
We use srec2flash and hex2flash to generate the .flash file, which contains boot_monitor commands, such as r0, e00xxx,.... How can we get the whole flash image file that we can program into flash directly? Thanks! hjia
Honored ContributorSince you your project is based on nios I, you can not use the flash programmer tool under nios II IDE where flash programming is much more easier.
But even if you use nios I, you are not forced to program flash by using normal programmer. You can burn your hardware, software and other images to flash seperately by using RS232 UART. It's applicable in spite of slowness. Attention: You shall put the images to their appropriate locations.Honored ContributorYes, we are now using UART to program flash.
But what I mean is to program the flash thru the Stand-alone Universal Device Programmer for mass production. This programmer is a hardware as Altera APU. .flash file is not a normal hexadecimal file which can be programmed by a programmer. Then how can I get a hex file from a .flash file for programming? Thanks! hjiaHonored ContributorHi hjia,

Are you referring to intel hex format? Regards, --ScottHonored Contributorhjia, One idea, since you can program your plug-in flash using the uart, you could do that first and then remove the chip and read its contents in your universal programmer. You could then save the file in any format supported by the programmer.

--scott --- Quote End --- Hi Scott, Can we only program the SREC to flash? I know that the .flash file has a boot command attached at the upside of .srec, which cannot be used by a programmer. If we only download .srec to flash, can Nios run at power up automatically? Also we have FPGA configure contents in this flash. SOF can be converted to HEX. Regards, Hjia

Duh, sorry ... the flash file is an srec. --Scott
