TBS 5930 (m88rs6060) + Radxa ROCK3 Model A boot fail #310
Comments
Same issue in #329 with Orange Pi 5 Plus under 6.6 next |
hi all! |
Interesting that this is not aarch64 specific in your case, I was thinking this was going to be a weakly ordered specific race condition. |
as far as i understood kernel crashes in loading module in cold state and could not read eeprom |
module crash on tbs5930_frontend_attach() |
HI dear crazycat69 -thanks for the answer |
But demod chip also not answer. This some USB host issue, maybe incomplete SoC init when DVB device init started. |
thanks for the answer! is there any way to init demod chip after complete boot? |
1.) Add the line blacklist dvb-usb-tbs5930 into the file /etc/modprobe.d/blacklist.conf 2.) Add the line /sbin/modprobe dvb-usb-tbs5930 into the file /etc/rc.local P.S. How to Enable /etc/rc.local with Systemd. Usual rc.local enabled by default |
Hi thanks for this hint |
Hi Dear crazycat69 |
Now connected 5530.
|
hi dear crazycat69! |
another thing!
please tell us what this mean?
are you reconnect usb cable manually or by the software? |
5530, 5930, 5230 use same PCB, but 5230 and 5930 have soldered only ter/cable or sat part. |
First time device detected in cold state (Cypress FX2 without firmware), next step firmware load and FX2 MCU reset, next step first attempt EEPROM read and demod init - this failed and device disconnected by driver. P.S. This init sequence same since first TBS QBOX device. |
Well, look like 5930 driver bug :)
|
Via usb port under windows with standard driver + my soft based on StreamReaderEx-BDA. |
thank you dear crazycat69! |
Thank you, should be able to test this over the weekend. |
TBS USB devices have small 256 bytes EEPROM for FX2 config and some vendor info like MAC and windows driver mode (for 5530, 5230) |
thank you! |
Still seeing initialization issues for this device:
That's with media_build and media from master:

If I first turn on the TBS 5930 connected to the Rock 3 board and then turn on the board, then an error appears during the board boot. But if I turn on the TBS 5930 and connect to the Rock 3 board when my board is already on, then everything works fine.
