Re: [U-Boot] Issue in u-boot; TFTP error: trying to overwrite reserved memory...

Hello Christopher, hello SImon, today I debugged this problem, as tftp was not working in my u-boot SPL (AM335x based custom board) for the reasons described in this thread. It turns out that lmb_init_and_reserve() could not set proper values as bd->bi_dram[0].size = . The reason IMHO is

[PATCH v1 3/7] SST26* locking: need to enable write

prior to using the WBPR (write block protection register) command to write new block protection register values, the WREN command must be sent. otherwise the new values are not applied. Signed-off-by: Bernhard Kirchen --- drivers/mtd/spi/spi-nor-core.c | 8 1 file changed, 8

[PATCH v1 4/7] write WPEN bit for SST26* devices when locking

ng the IOC bit in SST26* devices' config register if any block is protected by "sf protect lock" command, thus enabling hardware write protection. this behavior is similar to the "sf protect lock" implementation for Micron (and compatible) chips. Signed-off-by: Bernhard Kir
