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-TX53-2014-11-14
13 - silence error message for i.MX53 mask revision 4
14 (refer to TX53-PCN-2014-11.pdf)
17 git tag: KARO-TX53-2014-08-15
20 - change pad settings for DDR control lines, to prevent memory
21 errors at high temperatures
24 git tag: KARO-TX51-2014-08-08
27 - explicitly program the padctl settings for SDRAM and NAND from
28 the DCD to ensure correct settings after soft reset.
29 - reduce DSE values for SDRAM and NAND control lines for better
30 error margins in NAND detection and SDRAM stress test.
31 - Revert the change of the NFC clock frequency from the previous
32 release, as this is not necessary any more with the improved
36 git tag: KARO-TX53-2014-04-09
39 - reduce the NFC clock frequency to 16MHz to prevent NAND chip
40 detection errors at cold temperatures with the Toshiba
41 TC58NYG0S3EBAI4 flash chips
43 - adjust core voltage according to selected frequency upon boot
44 - remove bogus DDR3 Write leveling calibration that is not
45 required due to the PCB layout and does not work with the
46 NT5CB128M16FP-DII chips
49 - committed the missing source code changes for v1.5.5 that were
50 only committed to the legacy CVS repository but missing in git.
55 - updated SDRAM initialization to work with NT5CB128M16 mask
56 revision 'F' (see: TX53-PCN-2013-08.pdf)
61 - workaround for MPLL restart problem in i.MX27 date code 1230
62 and newer (see /Documentation/TX27PCN2012-09.pdf).
63 - wait after enabling wdt clock in HAL_PLATFORM_RESET() to
64 prevent possible hang in 'reset' command.
65 - fix trampoline code change for archs that use the default
66 CYGARC_HAL_MMU_OFF macro.
69 Fixup messed up source code from previous release
74 - fixed the trampoline code in redboot_linux_exec.c
76 - fixed phys <-> virt address calculations
77 - added support for 2 memory banks (1GiB)
78 - fixed ATAG_MEM construction for banked memory
84 - add support for Toshiba NAND flash
85 - implement workaround for ENGcm12051 (DPLL: Meta-stability Issue)
87 - fix CCGR0 settings to enable JTAG interface
91 Fix FEC driver handling of 10BaseT link
95 Added support for TX53
100 Added support for redundant WinCE image load
105 Added support for splash screen, enabled with:
106 fconfig bootsplash_enable true
108 Name Default Value Description
109 lcd_bpp: 16 LCD color depth (only 16bpp for now)
110 lcd_buffer_addr: -2113929216 LCD frame buffer address (hex: 0x82000000)
111 lcd_clk_period: 33333 Pixel clock period (in ps)
112 lcd_clk_polarity: false Pixel clock polarity active low
113 lcd_panel_width: 640 LCD panel width (in pixels)
114 lcd_panel_height: 480 LCD panel height (in pixels)
115 lcd_hsync_polarity: true HSYNC polarity active low
116 lcd_hsync_width: 64 HSYNC pulse width (in pixels): 1 .. 64
117 lcd_margin_left: 96 Left margin (in pixels): 1 .. 256
118 lcd_margin_right: 80 Right margin (in pixels): 1 .. 256
119 lcd_margin_top: 46 Top margin (in scan lines): 0 .. 255
120 lcd_margin_bottom: 39 Bottom margin (in scan lines): 0 .. 255
121 lcd_vsync_polarity: true VSYNC polarity active low
122 lcd_vsync_width: 3 VSYNC pulse width (in scan lines): 0 .. 63
124 Image data is loaded from the flash partition named 'logo' and
125 can be stored either as a binary dump or in Windows .bmp
128 Renamed config/TX25-40x0.ecc to config/TX25-40x1.ecc to be in
129 sync with the module name
134 Added support for TX51-80x2 and TX51-80x1 (SDRAM clock selectable via cdl)
139 Fixed SDRAM timing according to application note from Micron.
141 Fixed display of reset reason.
142 Corrected DEBUG LED settings
144 Disabled FIS CRC check to facilitate update of the Linux
145 partition from within Linux (see RedBoot/README)
149 Added support for TX51-80x0
153 Corrected SDRAM timing setup for TX25 that was accidentally broken
154 in the previous release
158 switched to unified source tree for TX25,TX27,TX37
159 fixing some issues with bad block handling on TX27
163 Corrected the SDRAM initialisation for TX27-4021 (128MiB SDRAM)
168 Fixed a bug that lead to writing the RedBoot config partition on
169 every startup which would lead to excessive wearout of the flash.
170 The patch ecos-tx27-update.patch should be applied before compiling
175 + 'RedBoot config' partition merged with 'FIS Directory' into one
177 + improved bad block handling
178 + Flash partitioning changed due to the above
179 NOTE: The Linux kernel expects the RedBoot partition table at a
180 fixed block in flash determined by a configuration option.
181 Thus the new RedBoot version will only work with the new
183 + MAC address stored in processor internal fuse array
184 + new command: 'nand bad' to manually update the BBT
