Re: [U-Boot] access u-boot environment variables from kernel space
Dear All, I have to implement the jtag and execute XSVF file through diagnostic command from u-boot. the layout of our board as below: __ |_Processor| -> FPGA -> CPLD ^ | |__| I can able to get Device ID of both FPGA and CPLD but iam not able to execute XSVF file. when i debuged the code i found that it is expecting data from TDO line. but this is not happening. My question is: when i can able to get device id why can i execute the XSVF file NOTE: The state is moving As below xsvfDoXREPEAT xsvfDoXENDXR xsvfDoXENDXR xsvfDoXSTATE xsvfDoXSTATE xsvfDoXRUNTEST xsvfDoXSIR xsvfDoXSDRSIZE xsvfDoXSDRSIZE xsvfDoXTDOMASK xsvfDoXSDRTDO TAP State = DRUPDATE TAP State = RUNTEST/IDLE TDO Expected = 0xf4004093 TDO Captured = TDO Mask = 0x0fff xsvfDoXSDRTDO iErrorCode ERROR: TDO mismatch ERROR at or near XSVF command #10.See line #10 in the XSVF ASCII file. Upgarde the Image and RESTART !!! Regards Manukumar ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Have you looked at fw_printenv?

This is way the network driver goes. No, you get that from the device tree. You cannot rely on U-Boot to have initialized the network hardware, or on the network hardware to not have been reset since then. -Scott ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] access u-boot environment variables from kernel space
Dear All, How to access u-boot environment variables from kernel space or user space in P1012 processor. The variables required to be accessed from uboot environment section are: eth1addr serverip Note: Kernel version = 2.6.35 Regards Manukumar ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
