Hi,   Question about USB & BF-707, switching between USB Host vs Device mode. Historically, the USB ID-pin was dictating the mode thanks to the extra pin in the usb receptacle/cable.   Today with Type-C's DRP (dual role port), the configuration is done either via the passive CC1/2 pins or via the PD serial protocol.   Many Type-C detection… (Show more)

Sometimes, once a week or month, the processor hangs. Neither internal nor external watchdog doesn't brings it from that. Initially processor  generates an exception "undefined instruction". Exception routine runs an infinite loop. Then watchdog triggers reset. Processor starts from boot ROM, but boot ROM also don't see flash content and therefore… (Show more)

I am using a BF561 for a pretty large program and I have a large amount of data being written to my SDRAM (addr 0x00000000 to 0x01FFFFFF). I access that data through a pointer. There are times that it appears the data gets corrupted and I'm not sure why. Some sets of compiled code are good when I click the "internal SRAM and external SDRAM" radio… (Show more)

I am using a BF504F processor and trying to stream the data I collected from external ADC to an SD card. I used 2x8k L1 memory (core memory) sections as ping-pong buffers to stream the data. While the Sport read data from ADC to one memory section using DMA2, the DMA1 transfers the data in the other memory section to the SD card. My problem is… (Show more)

Hi! I have a custom board with BF527, 32 Mb SDRAM, RGB LCD (via PPI) and ADC(via SPORT1).   I setup and run DMA0 PPI: *pDMA0_CONFIG = 0; // обнуляем настройки DMA0 *pDMA0_PERIPHERAL_MAP = 0x0000; // подключаем DMA0 для PPI *pDMA0_NEXT_DESC_PTR = &LCD_descriptor_array[9]; *pDMA0_START_ADDR = &LCDActivePage[0]; *pDMA0_X_COUNT =… (Show more)
