Re: gles2 C framework now with raspberry pi support! :o

Hi. I cloned again, but it looks like the new makefile doen't create the target "o" directory. After creating that manually, the compile fails at the same point. Will have another look later. Regards.

Re: How do I reformat an sd card that no longer show in win

Hang on, wasn't the card recognised fresh out of the box by windows and your current reader? I've a couple of once-working & now apparently dead cards: one 4GB & one 8GB. Neither cause the reader's light to flash on insertion in either windows or RPi/linux. Same reader is happy with 16GB cards.

Re: can't build hello_pi examples in Raspbian

Yes, I was on arm_freq=850 with no other tweaks. Dropped it to 700 & hello_triangle now runs without freezing.

I tried hello_triangle2 - I get a still mandlebrot image. No freeze, can exit with ctrl-c, but wonder should I be seeing some animation?

Tks Dom

RETRACTION - DO NOT BUY THE ABOVE ITEM

I've now found that when the battery approaches full charge, bizarrely it causes the Pi to reboot.

Re: Overpromised and Underdelivered?

@ullix - what memory split are you using... I suspect the more common 224/32? The GPU needs more than 32MB for video decoding. Change your start.elf to one which allocates less memory to the arm, and more to the GPU.

Re: making custom .img's

To blank the free space you could use dd:
dd bs=1mb if=/dev/null of=somefile

Then remove the big file full of 0's:
rm somefile

As a bonus the image will zip up small cos of the now low-randomness in the empty space on the partition.

Re: RS232 Breakout Board

Yes, that"s the page. One can only hope that GPIO16 surfaces somewhere to allow modification by hand on the initial batch for those that need it, and that in future revs a way is found to route it to one of the spare header pins.
