DVflasher help

Hello Eric, We had the same trouble initially though we were using a Nand flash. We tried a few options on the DDR timings. Mainly, when we started to work with a 16-bit DDR2 interface mode and when we reduced the PLL1 multiplier, we found that the problem went away. But later we found

About SPI Driver

Dear Now I'm trying to write a simple SPI driver for controlling my own SPI peripheral. (with our custom board, not EVM) But I got some troubles... When I remove all SPI peripherals, I could still receive data from SPI_BUF !! As well as, I can read the SPI_BUF register, and SPI_BUF register

Optimizing bootup time

Hi all, I'm trying to optimize the bootup/load time (from power up to when the kernel and rc scripts finish loading) on our custom Davinci board. Our goal is to get it down to 10 seconds to close to that. I have tried a few stuff: 1) Remove/disable unnecessary features in u-boot 2)

RE: Optimizing bootup time

Hi! I use BusyBox in my installation and it is up and running very fast. Unfortunately I don't have precise numbers of boot time, but 10 sec seems right approximation to what I saw. My system runs from NFS and uses very small number of services, actually BusyBox starts its own getty and

Re: Optimizing bootup time

In addition to other recomendations 1. remove rc script and use manual boot script 2. remove udev and use static devices (3. compile modules inside kernel) (4. remove checksum check in u-boot) Tell me please: - what kernel do you use? - how log takes to mount JFFS2, and what is size of the

Reading data though DC4

Dear All, I have just started working on the DaVinci DVEVM and I am trying to read data from a device attached to the CCD controller and transfer this data to the DDR. I have look into some of the past discussions on this topic in the archives and have got a brief (but still very vague)

Re: Optimizing bootup time

Hi Constantine, I forgot to ask you. What do you mean by #1, using manual boot script? On our custom board, it seems like after the kernel loads, the scripts in /etc/rc.d/rcS.d are loaded, then the scripts in /etc/rc.d/rc3.d are loaded. Does switching to manual boot script really cut the

Jeremy, Regarding issue 1: This message is just a warning and will not have any effect of execution. The warning is coming because DSP/BIOS Link does not use the kernel build system and also it is not under the same license as the kernel itself. Regards, Deepali -Original Message-
