[U-Boot] mixed case DATA lines in kwbimage.cfg, and other file : cosmetic?
by David Purdy 28 Mar '12

28 Mar '12

Hi Prafulla & all, I understand that lower case hexadecimal for DATA lines is preferred for kwbimage.cfg (in Kirkwood). For a mixed-upper-and-lower-case kwbimage.cfg that is already in U-Boot, should I first submit a [PATCH][cosmetic] to change it to all lower case DATA? Or should this sort of change be considered as 'substantive'? I checked the Patches < U-Boot www.denx.de/wiki/U-Boot/Patches page for a reference to this, as well as the README.kwbimage file, but saw no reference regarding "case". I plan to reuse (though not replicate) the same kwbimage.cfg for two newer Seagate devices. thanks, regards, Dave

[U-Boot] [PATCH V2] Enable high speed support for USB device framework and usbtty
by Amit Virdi 28 Mar '12

28 Mar '12

From: Vipin KUMAR <vipin.kumar(a)st.com> This patch adds the support for high speed in usb device framework and usbtty driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board configuration files have to define this macro to enable high speed support. Along with that specific peripheral drivers also need to define a function to let the framework know that the enumeration has happened at high speed. This function prototype is "int is_usbd_high_speed(void)" Signed-off-by: Vipin Kumar <vipin.kumar(a)st.com> Signed-off-by: Amit Virdi <amit.virdi(a)st.com> --- README | 8 +++++++ drivers/serial/usbtty.c | 50 ++++++++++++++++++++++++++++++++++++++++++++- drivers/serial/usbtty.h | 4 +++ drivers/usb/gadget/core.c | 1 - drivers/usb/gadget/ep0.c | 23 +++++++++++++++++--- include/usbdescriptors.h | 15 +++++++++++++ include/usbdevice.h | 22 ++++++++++++++++++- 7 files changed, 116 insertions(+), 7 deletions(-) diff --git a/README b/README index b69a3b6..0ab6892 100644 --- a/README +++ b/README @@ -1148,6 +1148,14 @@ The following options need to be configured: Define this to have a tty type of device available to talk to the UDC device + CONFIG_USBD_HS + Define this to enable the high speed support for usb + device and usbtty.

Be sure to +run fdisk with the option "-u=sectors" to set units to sectors: + + * o ..................... create a clear partition table + * n ..................... create new partition + * p ............. primary partition + * 1 ............. first partition + * 2048 .......... first sector is 2048 + * +1M ........... make the partition 1Mb big + * t 1 ................... change first partition ID + * 53 ............ change the ID to 0x53 (OnTrack DM6 Aux3) + * <create other partitions> + * w ..................... write partition table to disk + +The partition layout is ready, next the special partition must be filled with +proper contents. The contents is generated by running the following command +(see chapter 2)): + + $ ./tools/mxsboot sd u-boot.sb u-boot.sd + +The resulting file, "u-boot.sd", shall then be written to the partition. In this +case, we assume the first partition of the SD card is /dev/mmcblk0p1: + + $ dd if=u-boot.sd of=/dev/mmcblk0p1 + +Last step is to insert the card into MX28 based board and boot. + +NOTE: If the user needs to adjust the start sector, the "mxsboot" tool contains + a "-p" switch for that purpose. The "-p" switch takes the sector number as + an argument. + +4) Installation of U-Boot for NAND flash +----------------------------------------------- + +To boot a MX28 based board from NAND, set the boot mode DIP switches according to i.MX28 +manual chapter 12.2.1 (Table 12-2), PORT=GPMI, NAND 1.8 V. + +There are two possibilities when preparing an image writable to NAND flash. + + I) The NAND wasn't written at all yet or the BCB is broken + ---------------------------------------------------------- + In this case, both BCB (FCB and DBBT) and firmware needs to be + written to NAND. To generate NAND image containing all these, + there is a tool called "mxsboot" in the "tools/" directory. The tool + is invoked on "u-boot.sb" file from chapter 2): + + $ ./tools/mxsboot nand u-boot.sb u-boot.nand + + NOTE: The above invokation works for NAND flash with geometry of + 2048b per page, 64b OOB data, 128kb erase size. If your chip + has a different geometry, please use: + + -w <size> change page size (default 2048 b) + -o <size> change oob size (default 64 b) + -e <size> change erase size (default 131072 b) + + The geometry information can be obtained from running U-Boot + on the MX28 board by issuing the "nand info" command. + + The resulting file, "u-boot.nand" can be written directly to NAND + from the U-Boot prompt. To simplify the process, the U-Boot default + environment contains script "update_nand_full" to update the system. + + This script expects a working TFTP server containing the file + "u-boot.nand" in it's root directory. This can be changed by + adjusting the "update_nand_full_filename" varible. + + To update the system, run the following in U-Boot prompt: + + => run update_nand_full + + In case you would only need to update the bootloader in future, + see II) below. + + II) The NAND was already written with a good BCB + ------------------------------------------------ + This part applies after the part I) above was done at least once. + + If part I) above was done correctly already, there is no need to + write the FCB and DBBT parts of NAND again. It's possible to upgrade + only the bootloader image. + + To simplify the process of firmware update, the U-Boot default + environment contains script "update_nand_firmware" to update only + the firmware, without rewriting FCB and DBBT. + + This script expects a working TFTP server containing the file + "u-boot.sb" in it's root directory. This can be changed by + adjusting the "update_nand_firmware_filename" varible. + + To update the system, run the following in U-Boot prompt: + + => run update_nand_firmware + + III) Special settings for the update scripts + -------------------------------------------- + There is a slight possibility of the user wanting to adjust the + STRIDE and COUNT options of the NAND boot. For description of these, + see i.MX28 manual section 12.12.1.2 and 12.12.1.3. + + The update scripts take this possibility into account. In case the + user changes STRIDE by blowing fuses, the user also has to change + "update_nand_stride" variable. In case the user changes COUNT by + blowing fuses, the user also has to change "update_nand_count" + variable for the update scripts to work correctly. + + In case the user needs to boot a firmware image bigger than 1Mb, the + user has to adjust the "update_nand_firmware_maxsz" variable for the + update scripts to work properly. -- 1.7.1
