From 1117cbf2adac59050af1751af6c6a524afa5c3ef Mon Sep 17 00:00:00 2001 From: Thomas Chou Date: Fri, 28 May 2010 10:56:50 +0800 Subject: nios: remove nios-32 arch The nios-32 arch is obsolete and broken. So it is removed.

Memory Organization -======================= - - -The heap is placed below the monitor (U-Boot code). - -Global data is placed below the heap. - -The stack is placed below global data (&grows down). - -3. CPU Variations -================= - -There are more than one NIOS CPU variation for the DK-1S10. U-Boot -supports the following CPU configurations: - - - Altera Standard 32 (make DK1S10_standard_32_config) - - Microtronix LDK 2.0 (make DK1S10_mtx_ldk_20_config) - -4. Examples -============ - -The hello_world example was never tested on DK-1S10. Neverthelse -it should work as far as possible, because the DK-1S10 port is -more than ninetieth percents equal to the DK-1C20 port and at -this platform the hello_world example was already tested -successfully (see README.dk1c20). - - -5. Programming U-Boot into FLASH with GERMS -============================================ -The current version of the DK-1S10 port with the default -configuration settings occupies about 78 KBytes of flash. -A minimal configuration occupies less than 60 KByte -(network support disabled). - -To program U-Boot into the DK-1S10 flash using GERMS do the -following: - -1. From the command line, download U-Boot using the nios-run: - - $ nios-run -r u-boot.srec - -This takes about 45 seconds (GERMS is not very speedy here). -After u-boot is downloaded it will be executed.

Quit nios-run and start your terminal application (e.g. start - Hyperterminal or minicom). - -3. Download the u-boot code to RAM. When using Hyperterminal, do the - following: - - a.

Copy the binary image from SRAM / SDRAM to flash: - - at the Altera Standard 32 to SRAM: - - ==> cp.b 800000 40000 ${filesize} - - at the Microtronix LDK 2.0 to SDRAM: - - ==> cp.b 1010000 8000000 ${filesize} - -U-Boot will now automatically start when the board is powered on or -reset using the Standard-32 configuration. To start U-Boot with the -Safe-32 configuration, enter the following GERMS command: - - + g 40000 -- cgit
