Thank you.
It's all about evk1050 after rework.
The SDK sample evkbimxrt1050_flash_component_nor works perfect.
SW7 set to

Nothing done except this.
Should it work? - SDCard, for example, flashed perfect when SW7 set to

And below please find MFG tools log (thought that boot is from fuse):
-------MCU device Register----------
OCOTP->UUID[31:00] = 0x65f82484
OCOTP->UUID[63:32] = 0x3b1739d2
SRC->SBMR1 = 0x0
SRC->SBMR2 = 0x2000001
BMOD[1:0] = 2'b10 (Internal Boot)
HAB status = Open
--------MCU Flashloader info-------
Current Version = K2.1.0
Target Version = T1.0.0
--------MCU device eFusemap--------
(0x450) BOOT_CFG0 = 0x0
(0x460) BOOT_CFG1 = 0x0
(0x470) BOOT_CFG2 = 0x0
BT_FUSE_SEL = 1'b0
When BMOD[1:0] = 2'b00 (Boot From Fuses), It means there is no application in boot device, MCU will enter serial downloader mode directly
When BMOD[1:0] = 2'b10 (Internal Boot), It means MCU will boot application according to both BOOT_CFGx pins and Fuse BOOT_CFGx
----------FlexRAM memory-----------
IOMUXC_GPR->GPR16 = 0x200003
FlexRAM configuration is from eFuse
OCOTP->MISC_CONF0[31:00] = 0x40
FlexRAM Partion =0000 - 128KB ITCM, 128KB DTCM, 256KB OCRAM
Thank you in advance.
