Hi Simon,
I'm calling spi_chip_select(bus) from set_speed or claim_bus
to get the cs value from sf probe.
Seems like it returns the maximum number as 254, when I debug
further seems like slave_platdata returns NULL
int spi_chip_select(struct udevice *dev)
{
struct dm_spi_slave_platdata *plat = dev_get_parent_platdata(dev);
/ * this plat data returns NULL */
return plat ? plat->cs : -ENOENT;
}
log:
zynq-uboot> sf probe 1:0
zynq_spi_ofdata_to_platdata: regs=e0007000 max-frequency=166666700
zynq_spi_set_speed: cs 254
zynq_spi_set_speed: regs=e0007000, mode=1000000
zynq_spi_set_mode: regs=e0007000, mode=3
zynq_spi_claim_bus: cs 254
spi_xfer: bus:1 cs:254 bitlen:8 len:1 flags:1
spi_xfer: Timeout! TX FIFO not full
SF: Failed to get idcodes
Failed to initialize SPI flash at 1:0 (error -1)
Any help?
thanks!
