Blacklist of locked Down Version´s of RK3188 CPU

AW: Blacklist of locked Down Version´s of RK3188 CPU

No wonder they all came from the same manufacturer
Only a different Brand.

Neomode

Yes, all cs968 seem to have the same manufacturer. They could give us a working kitat for their devices and the lock down will be no problem anymore, because Kitkat is much faster than Jellybean.
This would be a nice move after making a very good business. ;-)

I prepared a suite of kernels for patching with T override removed. The example above is one of the auto-switching kernels with override still in place. CPU will stay locked in that kernel but amending the DDR in table 9 will have an affect. Table 8 is the frequency for DDR for a non-T kernel.

I strongly suggest you use the kernels I prepare for patching, they are better builds and have CPU/DDR overrides removed.

OK. I wait for the kernels you prepare. I will patch it with your amended script after.
We speak about 6210 1080p/720p right ?

I think is 8 not 9 the ddr table.

leolas.

Leolas, they are both DDR tables as explained above.

Table 8 is DDR for RK3188
Table 9 is DDR for RK3188T

But, again, don't use that kernel use the special kernels provided in #614

Ok I can see now so thats run ok. Thanks. But now I see two tables for DDR in your "FAST" kernel and others ? 8 (8781576) and 9 (8781608) ?


== Table 8 at offset 8781576 ==
MHz mV
200 950 1 DDR_FREQ_SUSPEND
300 1000 2 DDR_FREQ_VIDEO
720 1200 256 DDR_FREQ_NORMAL

== Table 9 at offset 8781608 ==
MHz mV
200 950 1 DDR_FREQ_SUSPEND
460 1200 256 DDR_FREQ_NORMAL

== End of tables ==

So When rkpatchomatic ask to identify tables I can say that table 6 is for CPU, GPU for table 7 and DDR for table 9 ? right ?

Is Overclockomatic a good way for "T" models ? I mean to override "T" chip limitations ?

I do not see any GPU/DDR changes in tables for the kernel you build for me post 488 "kernel_16_1080_fast"

I tested the script and found a 'bug' (not really - more a required change). The DDR definitions have changed in KK beta. I've posted the changes required in KK kernels to PHJAnderson's thread. I'll post the full amended script below.

If this is not the done thing I'll delete the script.

No wonder they all came from the same manufacturer
Only a different Brand.

The NTFS and USB Ethernet are built in, you just need to patch the kernel frequencies to your own combo.

ha !

I see how to patch kernel to build CPU/GPU/DDR several combinations and I did it, but I do not see what to do for " USB ethernet support and full NTFS support - multiple partitions" ???

In other hand can you tell me wich frequencies you use to build a kernel for me "kernel_16_1080_fast" in your post 488 and witch table, 6-7-4 or 6-7-3 ?

thanks for that

Now it is official garbage from Rockship:-), but there is maybe a hint for the looping of all cs968 inside. Could the lan frequency be the cause of the loop?

Here the Statment from Rockchip about the T Version of the CPU:

Rockchip testing all stock of producing SoC's some stocks not passed tests for any reasons. Then RK cut the CPU and GPU frequencies for stability. And add an external frequency generator for LAN working. And call this - "low-consumption" version. In fact, it is rk3188 who not pass the tests.


Now we know what we have!
