RE: SPI flash drive implementation problem

Sorry for inconvenience Sir,

I was interfacing SPI flash memory with nRF52840. At the time of send command and register address to SPI flash, I defined NULL at *p_rx_buffer & rx_buffer_length because I wanted to only transfer data to flash. Once the command is successfully send to SPI flash then I want to receive data from flash memory. So I defined NULL at * p_tx_buffer & tx_buffer_length and trying to receive data at p_rx_buffer.

I didn't get proper data from flash but problem is resolved now.

Thanks for support.

Regards,

Pooja Uchagaonkar

[quote user=""]For SPI flash write functionality, only transmit functionality require to send address and data, so I defined receiving parameters are NULL herewith. Same reverse thing is apply at the time of receive. But I didn't get proper data when I am trying to read data from flash. [/quote]

I don't quite understand what you've done, can you re-phrase this paragraph?
