Well ...
This append when I'm at minimum CPU speed on my PC.
AMD 64 ondemand, no chance to load the firmware if fast load fail.
check_fw_load() failed.
I think that the first time i2c_master_send return a negative value
some bytes have been writen, no idea how many.
my test code :
int rc;
int localsize;
u8 *localdata;
rc= i2c_master_send(client, data, size);
if (rc != size) {
if (info->fastfw) {
if (rc < 0) rc=0;
CX25840_ERR("fast firmware load failed\n");
info->fastfw = 0;
cx25840_i2c_set_delay(client, 10);
localsize=size-rc;
localdata=data+rc;
loop=0; // just in case ...
do {
rc=i2c_master_send(client, localdata,
localsize);
rc == localsize ==1024, so, it's OK but check_fw_load()
failed.
that's all I can do today, it's 4h48 am and I'm pretty tired, sorry.
