[U-Boot] [PATCH] MTD/NAND: fix nand_base.c to use get_timer() correctly
by Reinhard Meyer 11 Dec '10

11 Dec '10

This is part of the timer cleanup effort. In the future we only use get_timer() in its intended way to program timeout loops. reset_timer() shall not be used anymore.

[U-Boot] [PATCH] usb_ether: register usb ethernet gadget at each eth init
by Lei Wen 09 Dec '10

09 Dec '10

Since the ether may not be the only one usb gadget would be used in the uboot, it is neccessary to do the register each time the eth begin to work to make usb gadget driver less confussed when we want to use two different usb gadget at the same time. Usb gadget driver could simple ignore the register operation, if it find the driver has been registered already.

[U-Boot] "usb reset" issue with some pen drives which work well in Linux/Windows
by Debashish Rath 09 Dec '10

09 Dec '10

Hello, I was trying to add usb support to u-boot for my Arm cortex-A9 processor based board. I am using "U-Boot 2009.08". I have tested the usb support (reset, fatls, fatload to boot linux etc) with the following devices and its working fine. 1. Western Digital "My Book" - Self powered USB HD 2. Western Digital "My Passport" - Bus powered USB HD 3. Transcend 4GB Pen drive - 2 makes However one issue still remains. It is not working with some usb pen drives (which works with Linux and windows). I have done the testing on 1. Dane-Elec 2 GB Pen drive 2. nxp 256 MB pen drive It seems these are some non-standard usb devices. With these devices uboot-usb is able to detect it, however during the mass storage scan, reset is getting failed (getting stall) and the following message we are getting: "scanning bus for storage devices... 0 Storage Device(s) found" Check the file - common/usb_storage.c. Function- usb_stor_BBB_reset : USB_STOR_PRINTF("RESET:stall\n"); I googled it however have not come across any fix so far. Then I took the latest u-boot i.e. u-boot-2010.09 and back ported the usb stack. With that the "usb reset" is a success and it is able to detect it as a mass storage device. Commands like "usb storage", "usb tree" etc showing proper information about the pen driver. However File System commands like "fatls" is not working. For USB support I have added the folling config stuffs to my file in include/configs #define CONFIG_CMD_USB #define CONFIG_USB_STORAGE #define CONFIG_USB_EHCI #define CONFIG_USB_EHCI_PNX84XX --> My usb config #define CONFIG_EHCI_HCD_INIT_AFTER_RESET #define CONFIG_SUPPORT_VFAT Is this a know issue or I am doing something wrong. Please help me in resolving this issue. Regards Debashish Rath Trident Microsystems
