SAM9 ISI and TCM8240MD camera

Development Boards MicroMod
1

i have been working with a sam9260 ek board and a tcm8240 MD camera with eclipse and sam ice tool everything is working just fine. i manage to get to work i2c comunication and configurating the camera to start sending frames but i think i have problems with de configuration of the isi periferial because in the buffer that is supposed to have the frames there are no frames

code :

unsigned int i;

unsigned int bufferIMG[1000000];

Async async;

unsigned int numErrors;

unsigned long temp=0;

PIO_Configure(pins, PIO_LISTSIZE(pins));

TRACE_CONFIGURE(DBGU_STANDARD, 115200, BOARD_MCK);

printf(“-- Basic TWI EEPROM Project %s –\n\r”, SOFTPACK_VERSION);

printf(“-- %s\n\r”, BOARD_NAME);

printf(“-- Compiled: %s %s –\n\r”, DATE, TIME);

// Configure TWI

// In IRQ mode: to avoid problems, the priority of the TWI IRQ must be max.

// In polling mode: try to disable all IRQs if possible.

// (in this example it does not matter, there is only the TWI IRQ active)

AT91C_BASE_PMC->PMC_PCER = 1 << AT91C_ID_TWI;

//CONFIG RST_CAM PIN

PIO_Configure(&ISI_RST, 1); // Configura Pin reset para camara como salida

PIO_Clear(&ISI_RST); // Camara en reset

can some one help with these has someo ne manage to make isi work with these cam?
Thx for the help :wink:

If you use the atmel isi driver you need to make sure it does not use has_emb_sync. That is, you want your isi to use hsync/vsync with pure data on the databus. No embedded start or stop of frame indications.

Then it should work if you have the right data-format.

I just wish I could configure the cams registers correctly. My images are pink while the test color bar images are perfect…
