1 RedBoot for Starter-Kit V (STK5)
4 ===========================================================
8 - updated SDRAM initialization to work with NT5CB128M16 mask
9 revision 'F' (see: TX53-PCN-2013-08.pdf)
14 - workaround for MPLL restart problem in i.MX27 date code 1230
15 and newer (see /Documentation/TX27PCN2012-09.pdf).
16 - wait after enabling wdt clock in HAL_PLATFORM_RESET() to
17 prevent possible hang in 'reset' command.
18 - fix trampoline code change for archs that use the default
19 CYGARC_HAL_MMU_OFF macro.
22 Fixup messed up source code from previous release
27 - fixed the trampoline code in redboot_linux_exec.c
29 - fixed phys <-> virt address calculations
30 - added support for 2 memory banks (1GiB)
31 - fixed ATAG_MEM construction for banked memory
37 - add support for Toshiba NAND flash
38 - implement workaround for ENGcm12051 (DPLL: Meta-stability Issue)
40 - fix CCGR0 settings to enable JTAG interface
44 Fix FEC driver handling of 10BaseT link
48 Added support for TX53
53 Added support for redundant WinCE image load
58 Added support for splash screen, enabled with:
59 fconfig bootsplash_enable true
61 Name Default Value Description
62 lcd_bpp: 16 LCD color depth (only 16bpp for now)
63 lcd_buffer_addr: -2113929216 LCD frame buffer address (hex: 0x82000000)
64 lcd_clk_period: 33333 Pixel clock period (in ps)
65 lcd_clk_polarity: false Pixel clock polarity active low
66 lcd_panel_width: 640 LCD panel width (in pixels)
67 lcd_panel_height: 480 LCD panel height (in pixels)
68 lcd_hsync_polarity: true HSYNC polarity active low
69 lcd_hsync_width: 64 HSYNC pulse width (in pixels): 1 .. 64
70 lcd_margin_left: 96 Left margin (in pixels): 1 .. 256
71 lcd_margin_right: 80 Right margin (in pixels): 1 .. 256
72 lcd_margin_top: 46 Top margin (in scan lines): 0 .. 255
73 lcd_margin_bottom: 39 Bottom margin (in scan lines): 0 .. 255
74 lcd_vsync_polarity: true VSYNC polarity active low
75 lcd_vsync_width: 3 VSYNC pulse width (in scan lines): 0 .. 63
77 Image data is loaded from the flash partition named 'logo' and
78 can be stored either as a binary dump or in Windows .bmp
81 Renamed config/TX25-40x0.ecc to config/TX25-40x1.ecc to be in
82 sync with the module name
87 Added support for TX51-80x2 and TX51-80x1 (SDRAM clock selectable via cdl)
92 Fixed SDRAM timing according to application note from Micron.
94 Fixed display of reset reason.
95 Corrected DEBUG LED settings
97 Disabled FIS CRC check to facilitate update of the Linux
98 partition from within Linux (see RedBoot/README)
102 Added support for TX51-80x0
106 Corrected SDRAM timing setup for TX25 that was accidentally broken
107 in the previous release
111 switched to unified source tree for TX25,TX27,TX37
112 fixing some issues with bad block handling on TX27
116 Corrected the SDRAM initialisation for TX27-4021 (128MiB SDRAM)
121 Fixed a bug that lead to writing the RedBoot config partition on
122 every startup which would lead to excessive wearout of the flash.
123 The patch ecos-tx27-update.patch should be applied before compiling
128 + 'RedBoot config' partition merged with 'FIS Directory' into one
130 + improved bad block handling
131 + Flash partitioning changed due to the above
132 NOTE: The Linux kernel expects the RedBoot partition table at a
133 fixed block in flash determined by a configuration option.
134 Thus the new RedBoot version will only work with the new
136 + MAC address stored in processor internal fuse array
137 + new command: 'nand bad' to manually update the BBT
