multi qspi flash support in cwtap

[liguangyu02]

On our product based on LS1043A, two different model of QSPI flash were used.

Now we got a problem that when do first programing with CWTAP, only one model flash could be selected.

Is there mechanism to selected flashing algorithm automatically?

Bellow is the script currently used.

Thanks!

I did this according to your adevice, the dropdown box show two flash now.

However, the auto selection seems not supported.

Auto selection is not supported, you need to select the appropriate flash manually.

Please refer to C:\Freescale\CW4NET_v2020.06\CW_ARMv8\Config\flash\algorithms\S25FS256S.xml to define your own QSPI device S25FS256S1.xml

Then add one more QSPI device in CW Target Initialization file.

if QSPI_BOOT:
# Add QSPI device
fl.add_device({"alias": "qspi", "name": "S25FS256S", "address": 0x40000000, "ws_address": 0x10000000, "ws_size": 0x1FFFF, "geometry": "8x1", "controller": "QSPI"})

fl.add_device({"alias": "qspi", "name": "S25FS256S1", "address": 0x40000000, "ws_address": 0x10000000, "ws_size": 0x1FFFF, "geometry": "8x1", "controller": "QSPI"})
