20 years agoHi:
Thank you very very much! Scott:) My board is UP3,with Cyclone EP1C6Q240(with CPU 48MHz),TC58FVT160 Flash Memory 2MB(1M*16b),1S42S16400B SDRAM 8MB,128KB(64K*16b) SRAM. So i should create a suitable u-boot for this board,because u-boot-nios2-src just has the pci5441 and pk1c20. And i should modify the sample files, and fit it to UP3. 1:<target_board>.h include/configs/up3.h 2:<target_board>.c board/up3/up3.c 3:flash driver board/up3/flash.c The first problem is that i can't find the up3-flash datasheet(TC58FVT160), to use in the flash.c. No help in the UP3 munual reference. And in the work of creating up3.h,just getting little info from the SOPC Builder,a exiting up3_board example.Just like the below info: CPU: Clock 48.0MHz Base 0x00000000 End 0x000007FF jtag_uart: JTAG UART Base 0x00000800 End 0x00000807 ext_ram:Sram_UP3 Base 0x00020000 End 0x0003FFFF So the second problem is where can I find some details using for this u-boot work,such as, CFG_Nios_CONSOLE,CF G_GBL_DATA_OFFSET,CFG_Nios_TMRBASE,CFG_Nios_TMRIRQ and so on, because the UP3 munual reference doesn't have this data. Thank you again~! Regards! Justin
