Hi,

can I someone tell me, or give me developer contact to ask if OpenPLI supports X16 nand access?. It looks like many of the scripts are hardcoded for X8 nand access. I've replaced the nand in my box (see my other post) and it looks like my issues are down to the new nand being in X16 mode and not x8.

Anyone?

Hi,

I have replaced the nand in my machine (due to too many bad blocks) and have compiled a custom spin of OpenPLI so that I can recover my box.

According to this spansion document, it should be a drop in replacement

http://www.spansion....34ML01G1_AN.pdf

Its not a drop in replacement and I had to tweak the buildscript (why????), I am able to build a fully working image by tweaking the vu inc file  (conf/machine/include/vuxxo.inc) like so

The default values dont work for me, even though this replacement nand SHOULD have been a drop in replacement for the old nand (which is EOL). What I'm finding is the image compiles fine, mkubfs makes the image. The machine FULLY boots, but after booting up the nand is corrupted by some process (the nand resize perhaps?). I dont know how to proceed from here

 

brcmnand_handle_false_read_ecc_unc_errors: Uncorrectable error at offset 3bee000

 

 

I've attached a full log of the boot captured from the serial port and would REALLY appreciate it if someone who understands nand layout can tell me what's wrong. There are two logs, one that shows me flashing (without issue) and one of the boot showing the machine boots and then something bombs out and corrupts the nand. I have to flash with USB again to recover to allow box to boot

 

 

Hi,

I wish to get hold of the source code of openpli to compile a version of it myself. I need to do this because I've replaced the nand in my vu uno and I need to tweak the build script to deal with the new nand layout.

I tried to clone from

[user@server tmp]$ git clone https://github.com/openpli
Initialized empty Git repository in /tmp/openpli/.git/
error: The requested URL returned error: 403 Forbidden while accessing https://github.com/openpli/info/refs

Can someone tell me where the src code is?, sorry if its obvious but from reading around I cant figure it out.
