Re: Linker Error

Hi! Great that you made it to work!. Hmm, so it was the AudioInit thing after all... I was really dumbstruck as to why just initializing the audio in your boot.dlx and then setting the pins didn't work, and, hmm, still am.. I guess something triggers a complete restart of the audio at some point. Bu...

Re: Linker Error

Hmm, do you have the VS1010 Handbook? Various functions in the ROM configure various parts of the chip to various purposes as needed. What you are experiencing is the IOCTL_RESTART function of the audio output, which sets up DAC, analog drivers and I2S output in SRC mode. The problem probably goes a...

Re: Linker Error

Hmm, are you using a generic (compatible) app template? I think you need to use a ROM-specific app template to access most ROM functions. If that is the case, then the fix is to use a VS1010D -specific template for the project. That will include vs1010d_romabs.o or something that has the symbols. -P...

Re: VS1010 and eMMC

Great! And thanks for your feedback! In this boot.dlx, can the GPIOs be set to to turn on or off LEDs? Yes, please use the boot.dlx solution from the previous post as basis for writing your own firmware. I will help, of course. Hmm, one thing came to mind.. VS1010 SD driver also supports 4-bit mode ...

Re: VS1010 and eMMC

Hi! Sorry, I am in a hurry, but here's a quick follow-up. I got your board and was able to run the formatter on it. I had to use the command line version of the debugger (VS3EMU) instead of the VSIDE because I had some problems connecting to the board and had to do it step by step. It may be due to ...

Re: VS1010 and eMMC

Found it. Or so it seems, at least. Such a small bug, such bitter consequences. Anyway, it turns out that the VSOS SD init doesn't set the proper device flags (PRESENT, OPEN, SEEKABLE, READABLE and WRITABLE) if it doesn't find a valid filesystem (e.g. FAT). This happens when the eMMC chip contains a...

Re: VSMD001 - basic problem

Hi! Oh, hmm, Pasi, who has written the VS1000 software, is on holiday for a couple of weeks.. not sure if anything meaningful can be achieved before he comes back :( In the mean time, you can try to best build an idea of how the unit behaves - is is possible for you to revert the unit into a working...

Re: VS1010 and eMMC

Hi! Would it be helpful or possible for me to send one of the boards to VLSI for testing the communication between the eMMC and the VS1010 Yes, please do send it to us as soon as possible, I thought we already asked you to do this by email! Toshiba asked to confirm that CMD1 is sent repeatedly until...

Re: VS1010 and eMMC

Hi!

Wow, nice picture! I wish I had one of those when we wrote the SD init nearly 10 years ago ;)
What's the voltage level on the CMD, SDCLK and DAT0 lines? And VCC?

Re: VS1010 and eMMC

Hi!

What does the console say (TX0 at 115200 bps) ?

Please dump the entire console output here, there may be valuable info in it!
