[U-Boot] [PATCH 1/1] SPARC: fixes exported function stub for standalone applications. jmp ensures we get back to the location we came from, size(void *) make sure we get the function addresses correctly from the table (entry*4 instead of entry*1).
Hello Wolfgang,
This patch fixes the SPARC support for standalone u-boot applications.
-------------------- SPARC/LEON3 -------------------- => tftpboot 0x41000000 192.168.0.47:hello_world.bin Using GRETH 10/100 device TFTP from server 192.168.0.47; our IP address is 192.168.0.206 Filename 'hello_world.bin'. Load address: 0x41000000 Loading: # done Bytes transferred = 1232 (4d0 hex) => go 41000008 hej ## Starting application at 0x41000008 ... Example expects ABI version 5 Actual U-Boot ABI version 5 Hello World argc = 2 argv[0] = "41000008" argv[1] = "hej" argv[2] = "<NULL>" Hit any key to exit ...
## Application terminated, rc = 0x0 => -----------------------------------------------------
