[U-Boot-Users] What are IBAT and DBAT?
by Shawn 11 Jul '04

11 Jul '04

Hi, When trying to port u-boot to a MPC8245 card, I'm not sure what IBAT and DBAT register work for. For example, sl8245.h defines 4 regions of IBAT: SDRAM_BASE, 0x40000000, 0x80000000, and 0xf0000000. 1. Why are these regions defined? 2. Does it mean that you cannot access that memory area if the area hasn't been set by configuring IBAT and DBAT accordingly? 3. Can IBAT and DBAT be modified dynamically? For example, if I want to access 0x70000000 ~ 0x78000000 temporarily, which is not defined in configuration header file, can I change the configuration of one of IBAT and DBAT pair, e.g. ibat2 and dbat2? Thanks, -Shawn. __________________________________ Do you Yahoo!? Yahoo! Mail is new and improved - Check it out! http://promotions.yahoo.com/new_mail

[U-Boot-Users] [patch] add microblaze to mkimage
by Yasushi SHOJI 10 Jul '04

Hi, here is one liner to add microblaze support to mkimage. Again, string 'microblaze' is too long to break indentation. let me know if I should regenerate the patch to align the initializer. # it might be better for the record to split 'add new arch' and # 'reformat'.

[U-Boot-Users] PXA255 and I2C
by Herb Radford 10 Jul '04

10 Jul '04

I'm having some difficulty getting the I2C bus working on a PXA255-based board. I also find I'm somewhat confused by the documentation on the I2C in Intel's documents. I'm using an M41ST85 for the RTC chip. When I attempt to read from the RTC, I get timeouts and when I check the SCK, I find there's no activity at all. Digging into the documentation, it's not too clear how the GPIO's should be set for I2C. GP25 is the SSPTX pin which is (I assume) made bidirectional (somehow) when the I2C is enabled. Should it and GP23 (SSPCK) be set to alternate function 2 (I assume so)? I'm getting nothing on the I2C clock line when I transmit, but the I2C data line does go high when enabled. Puzzled, Herb
