I have carrier TE0703-06 and two modules: TE0820-03-2AI21FA (2CG) and TE0820-05-4DE21MA (4EV).
I'm using for corresponding board prebuilt images for QSPI and SD boot modes:
                test_board\prebuilt\boot_images\2cg_1i_2gb\u-boot\BOOT.bin
                test_board\prebuilt\boot_images\4ev_1e_2gb\u-boot\BOOT.bin

TE0820-03-2AI21FA works perfect.
TE0820-05-4DE21MA very unstable, mostly fails on FSBL or doesn't response at all.
Very often PS ERROR red LED (D3).
pmu_global.csu_br_error can be 80004b00 (for SD mode), 80009292, 80002400 (for QSPI mode).

Why TE0703-06+TE0820-05-4EV fails, although TE0703-06 has the same settings and TE0820-03-2CG works?

Hi Aleksei,
if I see it correctly, than you wrote to the technical support of trenz and a RMA was opened for this module with ZU4?
