the qspi connection uses a 16-bit spi bus, which is capable of transferring 8-bit bytes (lsb first). on j-link, the spi bus is addressable, meaning that the target is addressable by the sbc3036. the qspi spi bus can also be used to connect to a parallel nor flash memory. the spi connection is identified by the qspi0 interrupt line.


the spi flash connection is also exposed to the 0x64000000 region. the region is accessible via the qspi0_0 interface and is accessed by commands qspi_qspi_read/qspi_qspi_write. this region is byte-addressable, meaning that the target is addressable by the sbc3036. the region can be read and written to.


the connection to the qspi flash is detected by the qspi0_0_detect interface. the number of bytes transferred in one command can be controlled by the len parameter of the command. it must be a multiple of 16 (lsb first). if the len parameter is not set, the bus length is determined by the first 16 bytes read.


the address mapping for the qspi flash memory is accessed by the qspi0_0_get_addr interface. the first 16 bytes read return the address mapping for the region. the address mapping must be provided in the form of a binary number with a 24-bit binary number length. the address mapping for the qspi flash memory can be obtained for each region as well as for the whole memory.


the target of the qspi flash can be configured by the command qspi_qspi_write. if the target is the entire flash memory, the data is written to the entire flash. the first 16 bytes read returns the new data. 84d34552a1
