> We are developing a product which is based on the beagle bone black board. > > Currently we focusing our efforts to bring-up our board, which is based on the > beagle bone black device, But we are encountering the following problems: > 1. We notice that SPL (TI Uboot first stage) uses address 0x0038000 as a debug > trace log, when examine the AM3xx data sheet we found that address 0x0038000 > belongs to a memory section that is declared as GPMC external memory. > We couldn't find any volatile memory hardware that is mapped to the GPMC > external memory. We notice that Uboot SPL runs without any problems both the > beaglebone black and the beagle bone black Evb. However Uboot - SPL crashes > when accessing the GPMC external memory on our board, Can you help us resolve > it? > 2. How can we remove the beagle bone EEPROM (device ID chip) ? > 3. According to Beaglebone black when pushing S2 during boot up time The > processor internal ROM boot loader should perform the following boot sequence: > MMC1 -> UART, However we are unable to boot the "Uboot - SPL" through UART0 on > the beaglebone black board. > 4. How can be load a boot loader to address 0x402f0400 in the CPU internal > SRAM, Using the TI TAG model XDS100V2 and then launch it. (It seems that this > memory address is not accessible to TI Jtag debugger). If we can't can you > advice us how to debug Uboot - SPL using Ti Jtag? Have a look at the Code Composer Studio V5/6 GEL files to see how this can be done.
