UFS什么时候添加支持

技术大佬  UFS什么时候添加支持啊,这是一个新的种类,添加里可以增加T56卖点啊,很期待,很多手机UFS需要通过编程器调整后才能开成U盘。我认为UFS 可以优先于其他的芯片,毕竟这一块是在T56空白

I join the question above and ask too.  When you plan to introduce ufs support? At the moment, this is the most relevant and demanded memory standard.

研究了一下资料,工作量好大,一下还搞不了。

I understand that it's hard to do right away, but although you can make it clear to wait for ufs support at all or buy another programmer.

There is no need to wait for t56 to support UFS.
I can not  determine whether it can be supported. The differential signal of t56 FPGA can reach up to 960MHZ, but UFS requires 1.2GHZ. I wonder if UFS can work at low frequencies.

   总之还是希望您能尽力而为,曾经您说TL886II无法支持spi nand,可是连10块钱的CH341A 都已经被俄罗斯大佬开发出了支持SPI NAND的软件版本。

Maybe one of this document can help you understand how adding UFS to T56. Please give feedback about this. We wait. Great thanks.

这TL866II 逻辑上没有问题,但硬件因为有高压,而没有专门的高压隔离电路,影响了高速时的稳定性,所以无法支持,下一代TL866已在开发测试中,使用32位MCU,USB2.0 480MHZ通信,IO驱动隔离同T56,会全面支持SPI NAND。SPI NAND速度接近T56. 售价<300RMB

Thanks,I have these documents。

Maybe PWM-mode as in z3x can be supported. It used one differential line. And work in low speed.

PWM MODE speed is too low .  only support G4.  MAX 72MHZ

   A UFS device shall support the PWM‐G1 (default, mandated by [M‐PHY]), PWM‐G2, PWM‐G3 and PWM‐G4 GEARS. The PWM‐G5, PWM‐G6 and PWM‐G7 are optional.



A plan has been found. It can support HS-G1 on T56 (not tested yet), but due to the global lack of chips, it is now necessary to complete an additional task with a workload of 5 months, so it only be tested later.

OK. We just have to wait.
