i.MX233 package variants

[lategoodbye]

I have some questions about the i.MX233 package variants:

1. Is it possible to identify the the package variant (LQFP128, BGA169) of the i.MX233 via register?

2. How should be HW_CLKCTRL_ETM and HW_CLKCTRL_PIX treat on LQFP128?

Now i'm a little bit confused. According to i.MX23 reference manual chapter 6.4.2 there should be a register to identify the package variant (HW_DIGCTL_STATUS_PACKAGE_TYPE, 0=BGA, 3=LQFP), which is also in the bootlet code.

you are right, sorry I missed that:

HW_DIGCTL_STATUS[PACKAGE_TYPE]:  package type. 000=169BGA, 011=128TQFP

Table 6-4. HW_DIGCTL_STATUS i.MX23 Reference Manual (rev.1, 11/2009).

Hi Stefan

1. no

2. HW_CLKCTRL_ETM can be considered as reserved,

HW_CLKCTRL_PIX is functional, since LQFP128 supports

ITU-R BT.656 8-bit+clock mode according to Table 1-1. i.MX23

Functions by Package  i.MX23 RM.

Best regards
