_set_written: invalid block state(02) on ocssd12
my test program mainly test erase, write read functions by backend ioctl. and my qemu is ocssd12 branch. i run my qemu with parameters :
-device nvme,drive=myocssd,serial=deadbeef,lver=1,lba_index=3,nlbaf=5,lnum_ch=8,lnum_lun=4,lnum_pln=2,lsecs_per_pg=4,namespaces=1
and when i ran my test program on my qemu, errors happened: "nvm_be_ioctl.c ioctl_vio Failed:cmd->vuser.status:0xfc" "nvm_be_ioctl.c ioctl_vio Failed:cmd->vuser.result:0x2ff" "nvm_be_ioctl.c ioctl_vio Failed:NVME_NVM_IOCTL_SUBMIT_VIO err:-1, errno : Input outpur error"
besides, on my qemu terminal, it also shows errors: ppa:ch(1), lun(3) ... _set_written: Invalid block state(02) lnvm_rw: set written status failed
and what's going wrong when my qemu terminal shows "Could not read bb file"
Try using the latest master branch of qemu.
but my codes project is based on ocssd1.0. If i switch to qemu 2.0, seems like i have to modified a lot of my codes.
Most of the code above the lightnvm system speaks a neutral language that abstracts away the 1.2/2.0 specifics. Are you using that part?

i noticed that in 2.0 the geo structure includes "chunk punit etc" while 1.2 geo structure is "channel, lun, plane...". and in my project, my addresses are all in format of "channel, lun, planes.."
It should be straightforward to convert. The difference is in the planes, which is encoded into the sector.
grp = ch pu = lun blk = chk sec = plane + sec.

i try my qemu2.0, and write a simple test. But still shows error "segmentation fault"... in fact, in qemu1.0, it also shows "segmentation fault"(but in the "127.0.0.1:5900" terminal)
