   8 This file contains information regarding U-Boot and the Altera
   9 Nios Development Kit, Startix Edition (DK-1S10). For general Nios
  10 information see doc/README.nios.
  11
  12 Most stuff of this file was borrowed and based on README.dk1c20,
  13 the DK-1C20 related information file.

  33 2. Memory Organization
  34 =======================
  35
  36         -The heap is placed below the monitor (U-Boot code).
  37         -Global data is placed below the heap.
  38         -The stack is placed below global data (&grows down).
  39
  40 3. CPU Variations
  41 =================
  42
  43 There are more than one NIOS CPU variation for the DK-1S10. U-Boot
  44 supports the following CPU configurations:
  45
  46         - Altera Standard 32 (make DK1S10_standard_32_config)
  47         - Microtronix LDK 2.0 (make DK1S10_mtx_ldk_20_config)
  48
  49 4. Examples
  50 ============
  51
  52 The hello_world example was never tested on DK-1S10. Neverthelse
  53 it should work as far as possible, because the DK-1S10 port is
  54 more than ninetieth percents equal to the DK-1C20 port and at
  55 this platform the hello_world example was already tested
  56 successfully (see README.dk1c20).
  57
  58
  59 5. Programming U-Boot into FLASH with GERMS
  60 ============================================
  61 The current version of the DK-1S10 port with the default
  62 configuration settings occupies about 78 KBytes of flash.
  63 A minimal configuration occupies less than 60 KByte
  64 (network support disabled).
  65
  66 To program U-Boot into the DK-1S10 flash using GERMS do the
  67 following:
  68
  69 1. From the command line, download U-Boot using the nios-run:
  70
  71         $ nios-run -r u-boot.srec
  72
  73 This takes about 45 seconds (GERMS is not very speedy here).
  74 After u-boot is downloaded it will be executed. You should
  75 see the following:
  76
  77     U-Boot 1.0.2 (Jan 28 2004 - 19:02:30)
  78
  79     CPU: Nios-32 Rev. 3.3 (0x3038)
  80     Reg file size: 256 LO_LIMIT/HI_LIMIT: 2/14
  81     Board: Altera Nios 1S10 Development Kit
  82     In:    serial
  83     Out:   serial
  84     Err:   serial
  85     DK1S10 >
  86
  87
  88 2. Quit nios-run and start your terminal application (e.g. start
  89    Hyperterminal or minicom).
  90
  91 3. Download the u-boot code to RAM. When using Hyperterminal, do the
  92    following:
  93
  94    a. From the u-boot command prompt start a binary download to
  95       SRAM / SDRAM:
  96
  97       at the Altera Standard 32 to SRAM:
  98
  99         ==> loadb 800000
 100
 101       at the Microtronix LDK 2.0 to SDRAM:
 102
 103         ==> loadb 1010000
 104
 105    b. Download u-boot.bin using kermit.
 106
 107 4. From the U-Boot command prompt, erase flash:
 108
 109    at the Altera Standard 32 from 0x40000 to 0x5ffff:
 110
 111         ==> erase 1:4-5
 112
 113    at the Microtronix LDK 2.0 from 0x8000000 to 0x81ffff:
 114
 115         ==> erase 1:0-1
 116
 117 5. Copy the binary image from SRAM / SDRAM to flash:
 118
 119    at the Altera Standard 32 to SRAM:
 120
 121         ==> cp.b 800000 40000 ${filesize}
 122
 123    at the Microtronix LDK 2.0 to SDRAM:
 124
 125         ==> cp.b 1010000 8000000 ${filesize}
 126
 127 U-Boot will now automatically start when the board is powered on or
 128 reset using the Standard-32 configuration. To start U-Boot with the
 129 Safe-32 configuration, enter the following GERMS command:
 130
 131     + g 40000
