Greetings All,
I managed to corrupt the UBOOT on my EVM recently and I am still waiting
for delivery of my SDK to fix this. So I decided to look at UART
booting.
I have written a nice graphical application in Linux that can hopefully
be used to to restore the UBL via UART.
I am being a little
Can the User Boot Loader (UBL) be used to upload UBOOT, thus allowing
the user to restore UBOOT to flash?
Yes, load Rudy's UBL via uart. Then using Rudy's UBL load uboot.
Once you have uboot, you could write the uboot you have in memory to
nor flash using 'cp.b' command.

Carlos
Hi Paul, I figured that I have to send this email again as I did not copy the list in my last email, which I think might be useful for others. Sorry for duplicate emails to you. Here again, how I fixed it: 1. install DHCP server the same IPas TFTP server 2. use a static IP for the TFTP
I have written the equivalent in Linux and it appears to download
correctly, I get the 'DONE' Suggesting DaVinci has used downloaded the
the UBL but then it just starts again with the 'BOOTME'.
What are you sending as your header?
I send ACK 0BB80100
Are you sending your
Can anyone tell me if it is possible to create a DSP sever pjt on CCS3.2
with the Framework components, xDM algos, etc . Load it from CCS and
debug it while the arm app is running. If not is possible to generate
the DSP server on the linux environment and debug it from CCS.
Kind regards

This is Daniel, not Carlos. Im not
totally sure Im following whats going on. You have a program
that is being loaded by the RBL over UART or out of the NAND and into Internal
memory? The program should print hello and it does. But when
you try to run the program out of DDR, it doesnt work?
Hello
Just a quick thought before I go home.
Do you write the NAND OOB data with the ECC checksum?
Does the RBL and ubl_nand expect a valid ECC checksum?
I write the checksum (4 bytes starting at page offset 512).
Cheers
Rudy.

For a UBL data that goes into the NAND, no checksums or anything are
required. Checksums and CRC-32 checks are used over the UART because
data integrity is considered much more suspect.
Ah! Now I understand your question. The answer is I don't know. I sent
an email to someone who might know
Hi All,
I used Davinci EVM board development tools (Montavista arm_v5t_le-gcc) to
compile and created driver modules. Got errors as follows.
Seem like not matched the kernel and/or compiler,... ?
Any ideas, very appreciate.
Thanks,
Andy

Could somebody kindly tell me where or how could I find SW3-4? Where could I find description of these switches? I know the questions sounds stupid. Thanks for your help. JC
Do you Yahoo!?

Title: Re: where is SW3-4 in order to run demo on DVEVM1.1 update
SW3-4 is the red component in the center of the board. The silkscreen shows the switch position, cout4.
