[U-Boot] USB mass storage gadget patch
by victor 22 Nov '12

22 Nov '12

Lukasz, I am looking at the usb mass storage gadget patch from you at: http://patchwork.ozlabs.org/patch/104516/ I am trying to use this patch in the u-boot. Some questions: 1) Is this patch in U-boot git release? 2) Now I can use the patch and process till SCSI MODE_SELECT_6 command, and then problem is encountered. Basically the SCSI MODE_SELECT_6 is sent to EP1 Out, then data is sent to EP1 out, and the fsg_main_thread only sees the data. I change the code to force the CSW. The changes are: 1) fix the buf pointer in scsi inquiry 2) fix the buf pointer in scsi read format capacities 3) fix the buf pointer in CSW sending 4) fix attention condition checking in scsi command check 5) fix the context pointer before queue a request to read bulk only CBW 6) change bulk out endpoint from endpoint 2 to endpoint 1 to accommodate gen2 usb hardware limitation 7) in pad_with_zeros(), comment out the bh->inreq->length = nsend 8) in received_cbw(), force to send CSW if CBW is invalid. Otherwise, the IRQ routine keeps on reading the same data. I attach the file for your reference. Please kindly advise me. Thanks.

[U-Boot] [RFC PATCH 00/50] net: net subsystem ops cleanup
by Tomas Hlavacek 22 Nov '12

22 Nov '12

This patchset is a first stage of preparation of the net subsystem for the driver model. The idea of this patchset is: 1) Remove ops .init, .send, .recv and .halt from the eth_device struct. Add a sparate structure eth_ops which is ready for inclusion to DM core. 2) Replace dynamic init of ops function pointers by static struct. 3) Do minor style cleanup.

[U-Boot] [PATCH] serial: serial_sh: bugfix: autoboot fails if serial console is not connected
by Tetsuyuki Kobayashi 21 Nov '12

21 Nov '12

On kzm9g board (rmobile SoC), autoboot fails if serial console cable is not connected. When serial cable is not connected, serial error occurs and some garbage comes in data register. sh_serial_tstc() in serial_sh.c does not check error status and misunderstand there is some input data. It is the reason that autoboot fails. This patch adds checking error status in sh_serial_tstc(). This patch is based on v2013.01-rc1 tag of u-boot master git.

[U-Boot] [PATCH] am335x_evm: Fix Ethernet LED issue on BeagleBone
by Andrew Bradford 20 Nov '12

20 Nov '12

The default value for PRM_RSTTIME1 on am335x is 0x06 leading to a very short assertion of SYS_RESETn on BeagleBones. For PRM_RSTTIME1 values less than 0x80, some BeagleBones will end up with inverted Ethernet LEDs upon warm software reset leading to incorrect display of the Ethernet link status on the Ethernet jack. Extend PRM_RSTTIME1 to 0x80 to provide a longer assertion of SYS_RESETn allowing the SMSC PHY more time to sample the strapping resistors which set the LED orientation.

[U-Boot] analyze/change assembly code
by Gerlando Falauto 20 Nov '12

20 Nov '12

Hi all, we recently to had face some nasty issues, where for some reason two (functionally identical) versions of some code behave very differently. Namely, one version works and the other doesn't always work. It was clear from the beginning this was because of HW- (or compiler-) related issues. I thought it would then be useful to have a peek at what the compiler is doing behind the scenes, and possibly make some simple changes to the code. For instance, inserting some nops here and there, or reordering some instructions, may help in tracking down these different behaviors. I know the easiest way to LOOK at the file is simply to use objdump to disassemble an .o file. In the end I somehow managed to tamper with the makefiles so to get what I wanted for a given file, by adding a fake new ".s" target with the recipe to build it, and having the .o file depend on a ".S" file (which would be a manual/changed copy of the generated ".s" file) instead of the original ".c" file. This is however not linear and nice at all. So I was wondering whether there already is a well-established way of having the make process create (and keep) assembly files which can be then manually changed. Does my question make any sense at all? Any ideas? Thank you, Gerlando
