Other Parts Discussed in Thread: DLPA3005, , DLP4710
Hi,
I'm actually testing new TI firmware FWSel_DLPC3439_DLPA3005_pm2_i2c0x36_v7p7p0.img. Working just well, but compared to firmware dpp3439-dual-ASIC_7.3.2.img communication status (and short status as well) reports approximately every second Invalid Command Error (bit 0). The invalid command op-code is zero. It seems that error showed up after posting commands Write RGB LED Enable (52h) and Read RGB LED Enable (53h). In our aplication firmware every data written to DLPC3439 are verified a and communication (and other) status periodically checked, so new firmware doesn´t comply.
Next issue related to reading system temperature (D6h). Power of the temperature sensor normally comes from GPIO11, but in new firmware is off. After writing "1" to corespond GPIO using system commands is possible to power it up, but system command Read System Temperature (D6h) returned still the same value 6.5 degrees Celsius. Old fw works well.
Please TI help find a solution
Thank you very much
