1 RedBoot for Starter-Kit V (STK5)
4 ===========================================================
8 - workaround for MPLL restart problem in i.MX27 date code 1230
9 and newer (see /Documentation/TX27PCN2012-09.pdf).
10 - wait after enabling wdt clock in HAL_PLATFORM_RESET() to
11 prevent possible hang in 'reset' command.
12 - fix trampoline code change for archs that use the default
13 CYGARC_HAL_MMU_OFF macro.
16 Fixup messed up source code from previous release
21 - fixed the trampoline code in redboot_linux_exec.c
23 - fixed phys <-> virt address calculations
24 - added support for 2 memory banks (1GiB)
25 - fixed ATAG_MEM construction for banked memory
31 - add support for Toshiba NAND flash
32 - implement workaround for ENGcm12051 (DPLL: Meta-stability Issue)
34 - fix CCGR0 settings to enable JTAG interface
38 Fix FEC driver handling of 10BaseT link
42 Added support for TX53
47 Added support for redundant WinCE image load
52 Added support for splash screen, enabled with:
53 fconfig bootsplash_enable true
55 Name Default Value Description
56 lcd_bpp: 16 LCD color depth (only 16bpp for now)
57 lcd_buffer_addr: -2113929216 LCD frame buffer address (hex: 0x82000000)
58 lcd_clk_period: 33333 Pixel clock period (in ps)
59 lcd_clk_polarity: false Pixel clock polarity active low
60 lcd_panel_width: 640 LCD panel width (in pixels)
61 lcd_panel_height: 480 LCD panel height (in pixels)
62 lcd_hsync_polarity: true HSYNC polarity active low
63 lcd_hsync_width: 64 HSYNC pulse width (in pixels): 1 .. 64
64 lcd_margin_left: 96 Left margin (in pixels): 1 .. 256
65 lcd_margin_right: 80 Right margin (in pixels): 1 .. 256
66 lcd_margin_top: 46 Top margin (in scan lines): 0 .. 255
67 lcd_margin_bottom: 39 Bottom margin (in scan lines): 0 .. 255
68 lcd_vsync_polarity: true VSYNC polarity active low
69 lcd_vsync_width: 3 VSYNC pulse width (in scan lines): 0 .. 63
71 Image data is loaded from the flash partition named 'logo' and
72 can be stored either as a binary dump or in Windows .bmp
75 Renamed config/TX25-40x0.ecc to config/TX25-40x1.ecc to be in
76 sync with the module name
81 Added support for TX51-80x2 and TX51-80x1 (SDRAM clock selectable via cdl)
86 Fixed SDRAM timing according to application note from Micron.
88 Fixed display of reset reason.
89 Corrected DEBUG LED settings
91 Disabled FIS CRC check to facilitate update of the Linux
92 partition from within Linux (see RedBoot/README)
96 Added support for TX51-80x0
100 Corrected SDRAM timing setup for TX25 that was accidentally broken
101 in the previous release
105 switched to unified source tree for TX25,TX27,TX37
106 fixing some issues with bad block handling on TX27
110 Corrected the SDRAM initialisation for TX27-4021 (128MiB SDRAM)
115 Fixed a bug that lead to writing the RedBoot config partition on
116 every startup which would lead to excessive wearout of the flash.
117 The patch ecos-tx27-update.patch should be applied before compiling
122 + 'RedBoot config' partition merged with 'FIS Directory' into one
124 + improved bad block handling
125 + Flash partitioning changed due to the above
126 NOTE: The Linux kernel expects the RedBoot partition table at a
127 fixed block in flash determined by a configuration option.
128 Thus the new RedBoot version will only work with the new
130 + MAC address stored in processor internal fuse array
131 + new command: 'nand bad' to manually update the BBT
