LS2088A can not bringup and qspi flash can not be erased

[QiujuYe]

Hi ,

I use flexbuild_lsdk1812 to build an original firmware,  firmware_ls2088ardb_uboot_qspiboot.img, than update to our board and reset, the board can not bringup,  so I use programmer to program qspi flash image which can bringup, but the qspi flash can not be erased, then failed to program good qspi flash image to run again.  our qspi flash type is MT25QU512 as flowings, the pin 9 is used as data, but I am not sure, whether the original building image compiles this pin as write protect default, so the flash can not be erased by programmer?

Regarding the procedure of flash programming, please refer to section "7.7 Using flash programmer from eclipse IDE" in document Freescale\CW4NET_v2020.06\CW_ARMv8\ARMv8\Help\PDF\ARMv8_Targeting_Manual.pdf.

In Target Initialization file, please configure "USE_SAFE_RCW = True" to use hard-coded RCW on the target board.

In function Config_Flash_Devices in Target Initialization file, please modify QSPI flash device as the following.

fl.add_device({"alias": "qspi", "name": "MT25QU512ABA", "address": 0x20000000, "ws_address": 0x18000000, "ws_size": 0x1FFFF, "geometry": "8x1", "controller": "QSPI"})

Hi Yiping Wang,

Thanks for you reply.  We don't have the CodeWarrior Tap,  our flash programmer is Dediprog SF600, this programmer cannot erase the qspi flash, so have other ways?

Hello Qiuju.ye,

Please use your flash programmer tool to do "unprotect" action first, then do flash erasing. Image firmware_ls2088ardb_uboot_qspiboot.img cannot impact the flash. You also could contact DediProg.

Thanks,

Yiping

Hi Yiping Wang,

Thanks very much, I have found the question. The DediProg software version is too old, we upgrade the software from sf6.0 to sf7.2.x.x, then the flash can be erased and program well.
