[U-Boot-Users] [PATCH] cmd_bmp: Add support for displaying gzip compressed bmps
by Haavard Skinnemoen 09 Jan '08

09 Jan '08

From: Hans-Christian Egtvedt <hcegtvedt(a)atmel.com> The existing code can show information about a gzip compressed BMP image, but can't actually display it. Therefore, move the decompression code out of bmp_info() and use it in bmp_display() as well in order to display a compressed BMP image. Also, clean things up a bit and fix a memory leak while we're at it. [hskinnemoen(a)atmel.com: a bit of refactoring] Signed-off-by: Haavard Skinnemoen <hskinnemoen(a)atmel.com> --- One thing I can't help wondering about: What is the difference between "LCD" and "video"?

[U-Boot-Users] [FEC] Fix and optimize MII operations on FEC (MPC8xx) controllers
by Guennadi Liakhovetski 09 Jan '08

09 Jan '08

This patch fixes several issues at least on a MPC885 based system with two FEC interfaces used in MII mode. 1. PHY discovery should first read PHY_PHYIDR2 register and only then PHY_PHYIDR1 like cpu/mpc8xx/fec.c::mii_discover_phy() does it, otherwise the values read are wrong. Also notice, that PHY discovery cannot work on MPC88x / MPC87x in setups with both FECs active at all in its present form, because for both interfaces the registers from FEC 1 are used to communicate over MII. 2. Remove code duplication for resetting the FEC by isolating it into a separate function. 3. Initialize MII on FEC 1 when communicating over FEC 2 in fec_init(). 4. Optimize mii_init() to only reset the FEC 1 controller once. 5. Fix a typo in mii_init() using index i instead of j thus potentially leading to unpredictable results.

[U-Boot-Users] MII / RMII
by Guennadi Liakhovetski 08 Jan '08

08 Jan '08

Hi, 1. Does it make sense at all to define CONFIG_RMII without defining CONFIG_MII? The question is meant not really theoretical as in what meaning RMII has, rather how the macro CONFIG_RMII is supposed to be used? For example, tests like #if defined(CONFIG_MII) && defined(CONFIG_RMII) isn't checking for CONFIG_MII redundant? 2. cpu/at32ap/at32ap7000/gpio.c also tests CONFIG_RMII. at32ap is an AVR32 CPU and this macro is only defined in a few MPC8XX configurations, so, this test doesn't seem to make much sense in the current tree. 3. drivers/qe/uec_phy.c tests CONFIG_RMII_MODE, which doesn't occur anywhere else in the tree. The driver is enabled in some MPC85xx and MPC83xx configs. 4. drivers/macb.c tests for "RMII or MII mode" by jest checking #ifdef CONFIG_RMII ... #else ... #endif i.e., not for #elif defined CONFIG_MII This driver is only enabled in include/configs/atstk1002.h, which is also an AVR32 config, and it neither defines MII nor RMII.

[U-Boot-Users] Linux kernel hang (infinite loop)
by Madhu Saravana Sibi Govindan 02 Jan '08

02 Jan '08

Hello all, I'm using U-boot to bring up a custom 440gp-based board. We are able to transfer the kernel image (uImage) to the target board's memory and jump to it. But, the kernel seems to hang after that. We have verified that the board info struct and the clock frequencies are ok. We also have a BDI2000 hardware debugger with us, but we are unable to set any breakpoints using this (both using telnet or using gdb). However, I can use the telnet interface and single-step the 440gp after it seems to hang. I found that 440gp is infinitely looping through the "DataTLBError" routine. It is unclear to me what might have caused this in the first place. Has anyone seen this behaviour before? We are currently working on getting breakpoints to work using the BDI2000. Any help is greatly appreciated. Regards, G.Sibi

Trying to move my boot to latest u-boot and I can't make command completion work. Does it work in current u-boot and what config options do you use? Jocke
