Hi, I would like to change all IRQ masking register (GPC_IMR) via MEMTOOL to investigate interrupt behavior.
However, I could not change these register value.
here is my test logs from my console.
=== TEST LOG ===
root@imx6dlsabreauto:# /unit_tests/memtool -32 20dc008=ffffffff
Writing 32-bit value 0xFFFFFFFF to address 0x020DC008
root@imx6dlsabreauto:# /unit_tests/memtool -32 20dc008 1
Reading 0x1 count starting at address 0x020DC008
If I tried GPC_CNTR modification via MEMTOOL same as above procedure,
I can change register's value successfully.
also, I have successfully modified registers value of GPC_IMR via "mw" command from U-BOOT prompt.
How do I change registers value of GPC_IMR via MEMTOOL from Linux BSP?
