A hexdump starting at 0x20000, displaying some sort of header and _suspiciously_ structured binary data.

Some strings located at around 0x28000, like: C:\Users\TTI2BP\rtc_sandbox\rbd_eol_stil_fsl_rsg_development_RWS_TTI2BP\rbd\eol\stil\fsl\EcuAbstractionLayer\MemoryHwAbstraction\Fee_Cfg\src\Fee.c Crc_cpu32 != NULL ((*MgntPtr_pcu32) % FLS_PAGE_SIZE) == 0 (ListType_cu8 == RBC_PDM_IS_LIST_TYPE) || (ListType_cu8 == RBC_PDM_IS_ID_TYPE) 507501D0301 507_501_D_03_01, TTI2BP, 2017/02/16 10:50:32 560_560_D_05_01, leg2lr, 2017/10/17 11:50:55 360_363_D_29_01_P04, leg2lr, 2018/05/29 13:48:33 RSG01_B0001_182002_1742c_D1 2649011400

The firmware binary loaded into the GIMP raw image importer, set to 1-bit B/W. A wonderful tool to see repeating structures in binary data. The data looks _very_ structurized. There's no way that that's directly firmware... Depending on the struct size different patterns emerge. Sometimes it aligns with the selected image width, sometimes not, but it's all very repetitive.
