Re: UBL on custom board

Hello Ivan, The nand chip is a NAND01GR3B2BZA6E ST Micro part. It has a 8-bit bus width and the AEMIF is configured as 8-bit. The register BOOTCFG reads as 0x1F. Also, I use the same nand.c, nandcopy.c from the emulator and write the UBL code and u-boot code to the corresponding blocks

Re: UBL on custom board

Also, when I reduced my PLL1_Mult to 16 (for some 219MHz ARM operation) while keeping the PLL2_Mult at 22 (for 162MHz DDR2), I did get DVFlasher to read the magic number for u-boot and could get u-boot prompt, but with the same ECC error: nand_read_ecc: Attempt read beyond end of device

Problem with Uart Booting

Hi, I have tried TI's Document SPRAAI0 SPRAAI4 Downloaded code spraai4.zipit did not help me much. when i referred forum it got me going with Ruby's boot loader. Thanks to Ruby i am able to download u-boot image. But when i try to start u-boot with command u on the console i get BOOTME

Re: Problem with Uart Booting

Hi Allem, probably you are booting a u-boot which is compiled for flash boot. This one tries to copy itself from flash to RAM. You need a version which skips low level init (done by bootloader) and the selfcopy. Something like /* for Ram load version do not do low level init and do not

Audio glitch during volume control

Hi, I wrote below code to change the output audio volume. When I try to increase/decrease the volume while the audio is playing, I hear a glitch. Is there any solution to get rid of the glitch. int set_vol(int vol) { int mixerFd = 0; if ((mixerFd = open(/dev/mixer, O_RDWR)) ==

Re: UBL on custom board

Hi Ivan, Why would you want the gel file? When using this gel file and the JTAG, there are no ECC errors and the UBL and u-boot are flashed correctly using that. Regards Suba --- Ivan Tonchev [EMAIL PROTECTED] wrote: No, I have not modified the u-boot code yet. Will try that next.

Re: UBL on custom board

Hi Suba, Why would you want the gel file? I just wanted to compare it with the GEL files I use. I see that you modified PLL, DDR2 and AEMIF initializations. When using this gel file and the JTAG, there are no ECC errors and the UBL and u-boot are flashed correctly using that.

RE: UBL on custom board

Suba, I'm a little confused as to what method you are using to flash the NAND device via CCS. Also just so I'm clear, the problem statement is as follows: You have a 64MB custom board based on the DM644x, which is having problems when flashing and booting from the NAND device. The device

Re: UBL on custom board

Ivan, That also works fine. Just saw that there is an upgraded gel file in the spectrum digital site: http://c6000.spectrumdigital.com/davincievm/revf/ Have to check that out. Reg Suba. --- Ivan Tonchev [EMAIL PROTECTED] wrote: Hi Suba, Why would you want the gel file? I just

RE: UBL on custom board

Hi Daniel, Also, when printing out Ecc error, we print also the tempSpareValue which is always 0x while the eccvalue[i] has some value (masked as 0x0FFF0FFF). After flashing the code thro' CCS, the Nand_Init passes and the ECC error occurs on reading the magic number. If

Re: Problem with Uart Booting

Hi Rudy, I am using windows program which will connect to davinci and downloads the U-BOOT (u-boot_ram.bin) binary file. I have attached Windows program for your reference. I get this following log on the console. Can you please let me know if i am doing something wrong.
