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