[U-Boot] [PATCH V2] Nomadik: fix reset_timer()
by Alessandro Rubini 06 Nov '09

06 Nov '09

From: Alessandro Rubini <rubini(a)unipv.it> Previously the code wrote 0 to reset the counter and used negation to read an increasing value from the register. However, a readback before 400us still returned 0, which was reported as 1780 seconds, thus nand failed to work any now and then. As suggested by Wolfgang Denk, this changes READ_TIMER to just return the hardware counter (a declerasing one) and changes code using the value. Compile-tested only, at this point.

[U-Boot] [RFC 0/5] CAN framework for U-Boot
by Wolfgang Grandegger 05 Nov '09

05 Nov '09

From: Wolfgang Grandegger <wg(a)denx.de> This patch series adds a simple CAN framework for U-Boot. The main purpose is to do simple RX/TX testing when the device boots up but the interface functions could also be used for more complex tasks. This is just a RFC and a few more features need to be added or issues to be fixed, like using a generic device interface, if it already exists, and board specific device configuration, e.g. via i82527_register(addr, cfg-params). The sources are based on GPL v2+ code to be compatible with future U-Boot licence requirement. Please comment.

[U-Boot] [PATCH] use "boot selecr" jumper on NGW100 to select USART
by Thomas Sprinkmeier 05 Nov '09

05 Nov '09

Without the "boot select" jumper U-Boot will use the USART selected using the CONFIG_USART1, CONFIG_USART2, directive. If CONFIG_ALT_USART1 (or ..2, ..3, ..0) is defined then, with the jumper in place, that USART is used instead.

[U-Boot] standalone apps and their use of exported functions
by Valentin Ecker 05 Nov '09

05 Nov '09

Hey there! I am trying to customize/extend uboot with a standalone application which is automatically loaded before booting the kernel. Is there any way i can safely access uboot functions besides the exported(include/exports.h) ones? e.g. functions that can be executed from the command line - like nand copy, saveenv,... ...Im really doing hard on finding some documentation about this subject. thanks, Valentin
