Then everything is OK. Thanks.

Now it works fine! Good job. But I would not recommend anyone to use the cache of directory tree. In my experience, the most useful gives "cluster link map table" for an every opened file (not very small). You can see this feature (fast seek) in the library fatfs by ChaN . It's really impr...

I parse it all at once to create a Directory tree where the nodes are either files or folders. This makes it faster to access files and folders later on when you read and write. I did not stress test the function that parses a sd card will many sub directories. The function that parses directories ...

Good job, but I have problems at mounting filesystem: FAT2FS Boot Sector: Boot JMP: eb:0:90 OEM Name: Bytes Per Sector: 512 Sectors Per Cluster: 64 Reserved Sector Count: 6288 Table Count: 2 Root Entry Count: 0 Total Sectors 16: 0 Media Type: f8 Table Size 16: 0 Sectors Per Track: 63 Head Side Count...

I found a bug, memory is freed multiple times. Thanks for your help!

I see... Thanks!
I saw this file, just thought that the memory can be damaged.
This means that nothing bad happened, just the memory apparently freed 2 times instead of 1?

Hi! I have some errors at freeing memory, and not understand way this hapen. Thread 1/8c02943a freeing block @ 8c8e6038 'magic' is not correct! 8c8e6af8 Thread 1/8c029474 freeing block @ 8c8e6038 'magic' is not correct! 8c8e6af8 Thread 1/8c02943a freeing block @ 8c8e6038 'magic' is not correct! 8c8e...

I cannot find info for /res pin in this doc, unless it is SCK2/MRESET.

How this works? I cannot set low/high value to this pin? This input reset?

Hi all!
I can not find info for software control of the /res pin (num 9) in the serial port. Can anyone know? This is i/o or...?

DC SCIF Schematic:

Maybe I'm a little out of topic I write, but still. I also connected DC through the router. Maybe this is the cause of all my troubles with the network :) KOS network stack does not work even if I prescribe the settings manually (in bba code) instead of flash ISP. DC hangs... lwip stack works, altho...

I think yes.

I'm not sure what this will work faster than if i packed in to YUV422 on C and sended by DMA complete texture
It turns out that the conversion YUV420p to YUV422 simpler than the division into macro blocks, and sends by one request to the DMA, in contrast to the converter...

On ARM7TDMI 25MHz mp3 and aac decoders with asm optimizations works fine (128 kbps). But this asm optimizations doesn't supported on ARM7DI

ffmpeg works partially, there is a problem with auto detect format, I think you have a problem in that.
And I had to replace it mpeg audio decoder, the one that was in the library did not work for DC.

Thanks!
How can I replace these instructions? Specifically SMLAL and STRH?

What is different ARM7TDMI and ARM7DI? T and M extensions? What is?

I also tried to use the YUV converter, but faced the same problem. I complement the information contained here. You do not have enough interrupt: #define ASIC_EVT_PVR_YUV_DONE 0x0006 static semaphore_t *yuv_done; static void asic_yuv_evt_handler(uint32 code) { sem_signal(yuv_done); } // initializati...

Unfortunately could not test everything today. But concluded that the error occurs at the start of data transmission. Initialization works successfully. Once a request comes in, everything freezes. In the next few days will try to learn more.
