openfpgaloader got stuck when I load to Tang primer 20k

[huangshaoxin]

Jtag frequency : requested 6.00MHz -> real 6.00MHz
Parse file Parse /home/hsx/FPGA/linux-on-litex-vexriscv/build/sipeed_tang_primer_20k/gateware/sipeed_tang_primer_20k.fs:

DONE
Jtag frequency : requested 2.50MHz -> real 2.00MHz

the program got stuck here without any reactions

Could you try with --verbose-level = 2 and copy/paste display?

Also, could you try with master branch? Some issues was fixed in JTAG implementation.

Fixed; flash something on the flash (not sram), then unplug the power from the module and power it back. then flashing on SRAM regularly, works.
