LS1043AQDS: QSPI

[carlos-m-ribeiro]

Hello,

Can you help us about the reference/manufacturer of the QSPI that you used during the tests with LS1043AQDS u-boot?

Best regards

And would you know if these QSPI flashes are also compatible with LS1043AQDS: Winbond W25Q256JWEIQ and Macronix MX25L25635FZ2I-10G?

Thank you again

QSPI controller of the LS1043A has flexible sequence engine to support various flash vendor devices.

And you have any idea what can be wrong in our tests: using the QSPI flash MX25L25635FZ2I-10G and write the RCW file rcw_1600_qspiboot.bin.swapped from packages/firmware/rcw/ls1043aqds/RR_FQPP_1455/ in address 0x0, and u-boot.bin/u-boot-dtb.bin (generated using ls1043aqds_qspi_defconfig) in address 0x100000 we could not seen any output/print in our board.

Best regards

Using ls1043aqds in our board we can not seen any CPU accesses to QSPI, and we guaranty that bootstraps are correctly. What we should do to view CPU accesses to QSPI.

Thank you.

It is required to doublecheck the processor connection schematics referring the Design Checklist and evaluation board design files.

Also check that TRST_B is pulsed low (asserted) during POR sequence.
