1 RedBoot for Starter-Kit V (STK5)
4 The RedBoot source code is available via git from:
5 git://git.karo-electronics.de/karo-tx-redboot.git
8 ===========================================================
10 git tag: KARO-TX53-2014-08-15
13 - change pad settings for DDR control lines, to prevent memory
14 errors at high temperatures
17 git tag: KARO-TX51-2014-08-08
20 - explicitly program the padctl settings for SDRAM and NAND from
21 the DCD to ensure correct settings after soft reset.
22 - reduce DSE values for SDRAM and NAND control lines for better
23 error margins in NAND detection and SDRAM stress test.
24 - Revert the change of the NFC clock frequency from the previous
25 release, as this is not necessary any more with the improved
29 git tag: KARO-TX53-2014-04-09
32 - reduce the NFC clock frequency to 16MHz to prevent NAND chip
33 detection errors at cold temperatures with the Toshiba
34 TC58NYG0S3EBAI4 flash chips
36 - adjust core voltage according to selected frequency upon boot
37 - remove bogus DDR3 Write leveling calibration that is not
38 required due to the PCB layout and does not work with the
39 NT5CB128M16FP-DII chips
42 - committed the missing source code changes for v1.5.5 that were
43 only committed to the legacy CVS repository but missing in git.
48 - updated SDRAM initialization to work with NT5CB128M16 mask
49 revision 'F' (see: TX53-PCN-2013-08.pdf)
54 - workaround for MPLL restart problem in i.MX27 date code 1230
55 and newer (see /Documentation/TX27PCN2012-09.pdf).
56 - wait after enabling wdt clock in HAL_PLATFORM_RESET() to
57 prevent possible hang in 'reset' command.
58 - fix trampoline code change for archs that use the default
59 CYGARC_HAL_MMU_OFF macro.
62 Fixup messed up source code from previous release
67 - fixed the trampoline code in redboot_linux_exec.c
69 - fixed phys <-> virt address calculations
70 - added support for 2 memory banks (1GiB)
71 - fixed ATAG_MEM construction for banked memory
77 - add support for Toshiba NAND flash
78 - implement workaround for ENGcm12051 (DPLL: Meta-stability Issue)
80 - fix CCGR0 settings to enable JTAG interface
84 Fix FEC driver handling of 10BaseT link
88 Added support for TX53
93 Added support for redundant WinCE image load
98 Added support for splash screen, enabled with:
99 fconfig bootsplash_enable true
101 Name Default Value Description
102 lcd_bpp: 16 LCD color depth (only 16bpp for now)
103 lcd_buffer_addr: -2113929216 LCD frame buffer address (hex: 0x82000000)
104 lcd_clk_period: 33333 Pixel clock period (in ps)
105 lcd_clk_polarity: false Pixel clock polarity active low
106 lcd_panel_width: 640 LCD panel width (in pixels)
107 lcd_panel_height: 480 LCD panel height (in pixels)
108 lcd_hsync_polarity: true HSYNC polarity active low
109 lcd_hsync_width: 64 HSYNC pulse width (in pixels): 1 .. 64
110 lcd_margin_left: 96 Left margin (in pixels): 1 .. 256
111 lcd_margin_right: 80 Right margin (in pixels): 1 .. 256
112 lcd_margin_top: 46 Top margin (in scan lines): 0 .. 255
113 lcd_margin_bottom: 39 Bottom margin (in scan lines): 0 .. 255
114 lcd_vsync_polarity: true VSYNC polarity active low
115 lcd_vsync_width: 3 VSYNC pulse width (in scan lines): 0 .. 63
117 Image data is loaded from the flash partition named 'logo' and
118 can be stored either as a binary dump or in Windows .bmp
121 Renamed config/TX25-40x0.ecc to config/TX25-40x1.ecc to be in
122 sync with the module name
127 Added support for TX51-80x2 and TX51-80x1 (SDRAM clock selectable via cdl)
132 Fixed SDRAM timing according to application note from Micron.
134 Fixed display of reset reason.
135 Corrected DEBUG LED settings
137 Disabled FIS CRC check to facilitate update of the Linux
138 partition from within Linux (see RedBoot/README)
142 Added support for TX51-80x0
146 Corrected SDRAM timing setup for TX25 that was accidentally broken
147 in the previous release
151 switched to unified source tree for TX25,TX27,TX37
152 fixing some issues with bad block handling on TX27
156 Corrected the SDRAM initialisation for TX27-4021 (128MiB SDRAM)
161 Fixed a bug that lead to writing the RedBoot config partition on
162 every startup which would lead to excessive wearout of the flash.
163 The patch ecos-tx27-update.patch should be applied before compiling
168 + 'RedBoot config' partition merged with 'FIS Directory' into one
170 + improved bad block handling
171 + Flash partitioning changed due to the above
172 NOTE: The Linux kernel expects the RedBoot partition table at a
173 fixed block in flash determined by a configuration option.
174 Thus the new RedBoot version will only work with the new
176 + MAC address stored in processor internal fuse array
177 + new command: 'nand bad' to manually update the BBT
