Booting LS2085a with QSPI

jitenpatel — Sun, 08 May 2016 06:50:09 GMT

Hi, I am working on LS2085a based custom board. The board is designed taking LS2085aqds as a reference but we don't have NOR as well as NAND flash in our board.We are using QSPI as our main booting device.

I want to know what are the memory mappings required for QSPI boot. Can we use code warrior for flashing images to QSPI flash or any separate tool is required. Nothing is mentioned in the Code-warrior Development Studio for QorIQLS series - ARM V8 ISA Targeting Manual document that explains regarding flashing procedure for QSPI.

CodeWarrior for ARM contains Flash Programmer module capable performing SPI Flash programming.

Please refer to the ARM V8 ISA, Targeting Manual, 7.7 Using flash programmer from eclipse IDE. In the section "7.7.2 Device selection and information" it is explained how Flash device is selected and SPI Flash devices also could be chosen.

Thanks for your quick reply. we have already referred to the document mentioned by you but we are not getting QSPI flash in the device list. A snapshot is added below.

can you please tell what are the other options available to flash images to QSPI.

Please check whether used SPI Flash is compatible with one explicitly supported by the Flash Programmer.
