[U-Boot] BBT support to UBOOT question

Hi all, I'm not really sure as to the protocol for asking this question. So I'll go right ahead. I've seen code on the web written by open moko that tries to address the issue of adding BBT creation to the uboot nand command. I looked at the latest released uboot (2009.11.1) and I don't see the "

[U-Boot] Uboot RTC question

Hi, I am using Uboot 2008.10. I know its old but thats what we used when we started our project. My question is why is it that when we get to the Uboot prompt upon a power cycle, the date is set to: 2007-00-01 00:00:00 Where is that being set/initialized? I looked through the code and I can't de

[U-Boot] Preserving frame buffer memory between uboot and Linux

Hi, We have a situation when we want to display an image towards the end of Uboot's execution, before we boot Linux. I have that already. However, my issue is that while Linux boots it mallocs a new frame buffer and reinitializes the LCD controller with a new memory address. At the moment in Uboo

[U-Boot] potential Uboot Ping problem

Hi, It appears the ping in UBOOT is broken. The ping works fine if you have a network connection. But if the network connection is disconnected the ping hangs the system. There is no response to Control-C either. I have to power cycle the proto to get back to a UBOOT prompt. Is this a known issue

[U-Boot] Uboot bitmap utility

Hi, It seems that UBoot needs two data structures to display a bitmap in the framebuffer. Is there a utility that converts a Windows bitmap (BMP?) file and creates the 2 data structures that I can embedd in my code? Thanks, Steve -- View this message in context: http://www.nabble.com/Uboot-bitm

[U-Boot] UBOOT relocation question on Atmel arm926ejs

Hi, I am having a hard time understanding how the uboot relocation from flash to RAM happens. I'm trying to follow the code flow. I "think" I understand it, but wanted to run it by you experts to confirm. The flow starts in cpu/arm926ejs/start.s. In the reset function, after cpu_init_crit, u_boot

[U-Boot] Allocating a frame buffer in memory

Hi, I am trying to allocate a frame buffer for my LCD code. I think I understand how to set up the LCC controller in the Atmel AT91SAM9. So thats not the issue, at least not yet. I need to understand how UBoot allocates a block of memory for the buffer. My TFT/LCD is 320x240 and in 24 bit mode, s

[U-Boot] U-Boot makefiles question

Hi, I have a general question about the U-Boot Makefiles. When I want to add a file to one of the sub-Makefiles (such as in drivers/net/Makefile or board/atmel/at91/Makefile), it seems I need to go through several steps in order for the new file to get compiled. I must be doing something wrong

I see that this bundle is $2640US which is beyond my budget. I need to find another approach. Debugging with printfs is starting to bother me and waste time. Also, I am not totally familiar with GDB (GNU debugger). I may need to read a bit about it. thanks, Steve wd wrote: > > Dear

Hi, This question is related to U-boot; in particular debugging in a U-boot environment. I am working on U-boot for the first time as well as working with the Atmel AT91SAM9 processor. I am used to working with emulators when debugging low level code such as embedded diagnostics. I've never used

Hi, I see most of the POST tests relate to the PPC family. Is there a set of post tests based on the Atmel ARM9 family? Another related question: Is it assumed that POST runs before relocation or can some run after relocation? I would think that after you test memory before relocation, then it wo
